Description

Composite materials are created by combining two or more layered materials, each with different properties. These materials have become a standard for products that are both light and strong. Composites provide enough flexibility so products with complex shapes, such as boat hulls and surfboards, can be easily manufactured. Engineering layered composites involves complex definitions that include numerous layers, materials, thicknesses and orientations. The engineering challenge is to predict how well the finished product will perform under real-world working conditions. This involves considering stresses and deformations as well as a range of failure criteria. ANSYS Composite PrepPost provides all necessary functionalities for the analysis of layered composite structures.

ACP Tools (Draping, Rules, Rossete, Oriented selection set, Modeling Ply)
3 Lectures
49:46

** Level: Beginner **

Rosettes are coordinate systems that used to set the Reference Direction of Oriented Selection Sets. Rosettes define the 0° direction for the composite lay-up. Coordinate systems defined in Mechanical are imported by default. Additional Rosettes can be defined in ACP. There are 5 different types of Rosettes. The origin and directions of Rosettes are given in the global coordinate system. This Tutorial will help using edges to orient fiber directions. Very often fiber directions follow the outer structure of a design. To use this when defining fiber directions ANSYS Composite PrepPost can define the directions based on edges in the model.

**Agenda:**

- Define Stackups
- Define Edge Sets
- Use Edge Wise Rosettes to define Reference Directions

The ply application (draping) on doubly curved surfaces changes the theoretical fiber orientations. In many cases the effect is small and can be neglected. On the other side it is important to know how big this effect can be and if it has to be considered. ACP allows you to evaluate the draped fiber directions. In this tutorial we are going to model pressure vessel in design modeler in ANSYS software. Then we will apply composite layers on shell model. In the next step we are using different technique to analyzing draping in software.

**Agenda:**

- Define draping for modeling groups
- Select a seed point
- Show draped fiber directions
- Show draping shear
- Show and export flatwrap

Modelling Composite T-beam in ACP and Stress analysis in ANSYS
4 Lectures
56:24

** Level: Beginner **

An Oriented Selection Set is an Element Set with additional information about the element orientations. The orientation direction of an Element Set is responsible for setting the stacking direction of the associated lay-up. The Reference Direction is responsible for setting the 0 direction of the associated layup. These two directions must be defined while other parameters like Selection Rules and Draping are optional. The laminate is modeled by defining different Oriented Selection Sets for the different regions. The modeling plies are then associated with the OSS and their order defines the stacking sequence of the laminate. The OSS feature allows you to define several offset directions for one element: OSS can overlap and can have different orientations. In this tutorial we are going to model T-Beam by defining various oriented selection sets. This beam is made from three main parts which are: Top and middle surface, Bonding and covering layers.

**Agenda: **

• Using multiple oriented selection sets to define a complex composite layup

• Tapering of core materials

• Using multiple rosettes and different selection methods

Modeling model in ACP (Part 2)

15:53

** Level: Beginner +**

ACP has a pre- and post-processing mode. In the pre-processing mode, all composite definitions can be created and are mapped to the geometry (FE mesh). These composite definitions are transferred to the FE model and the solver input file. In the post-processing mode, after a completed solution and the import of the result file(s), post-processing results (failure, safety, strains and stresses) can be evaluated and visualized. After a completed solution, the post-processing is used to evaluate the performance of the design and laminate. The post-processing functionality for Solid Models of ACP allows the mapping of ply wise results on to the reference surface of the solid model. This ensures that also failures occurring inside the laminate can be observed and investigated. Failure criteria are used to evaluate the strength of a composite structure. Several failure criteria can be defined, combined and configured in the Definitions object. Failure criteria definitions can be used for failure plots and sampling points. The critical failure mode for an element shown in failure plots and sampling points is the one with the lowest reserve factor.

**Agenda **

• Connecting ACP to Static Structural Tools in Ansys

• Doing Stress Analysis

• Solving the model

• Analyzing Data in static Sturcutal

• Analyzing Data in Post-Processing

Eigenvalue and mode shape of Composite plate
3 Lectures
38:03

** Level: Intermediate **

Liner buckling (also noun as eigenvalue buckling) analysis estimated conceptual buckling strength of an optimal elastic structure. The eigenvalue can be calculated by the given constraints and system loading. In real-life nonlinear solution is utilized to obtain most accurate results- in comparison to linear solution. Thereby, this method is not suggested for precise buckling estimation. Moreover, some buckling problems just need to be solved with non-linear solution because it cannot be estimated with linear solution. Analyses that require upstream results from Eigenvalue Buckling or Pre-Stress Modal analyses are also supported and can be transferred from the solution.

**Supported Mechanical Systems for ACP models **

• Static Structural

• Transient Structural

• Steady-State Thermal

• Transient Thermal

• Modal

• Harmonic Response

• Random Vibration

• Response Spectrum

• Eigenvalue Buckling

The modal analysis technique is used to determine the vibration characteristics (I,e, Natural frequencies and mode shapes) of linear elastic structures. Our goal is to determine the first 10 natural frequencies and mode shapes for the plate with the hole shown. In this tutorial, first we are going to model simple plate with hole in ACP tools then we are importing model into modal. In the next step, we will have short introduction to modal tools in ANSYS software and do simulation to find natural frequencies and mode shape of composite model.

**Agenda:**

- Creating Plate with Hole in ACP
- Importing ACP model into modal analysis

**Level: Intermediate**

A harmonic analysis is used to determine the response of the structure under a steady-state sinusoidal (harmonic) loading at a given frequency. A harmonic, or frequency-response, analysis considers loading at one frequency only. Loads may be out-of-phase with one another, but the excitation is at a known frequency. This procedure is not used for an arbitrary transient load. vibration analysis should be always run prior to a harmonic analysis to obtain an understanding of the dynamic characteristics of the model. In this tutorial we are going to create composite beam then we will apply fixed-fixed boundary condition in modal section and find 5 mode shapes of beam. After finding mode shapes we will find harmonic response of beam under 250 N load applied on the two places in the middle of plate.

**Agenda: **

• Creating Composite beam in ACP

• Importing ACP model into modal analysis

• Finding 4 Mode Shape of Beam

• Determining the Harmonic Response

• Applying boundary conditions

** Level: Advance **

Meshes can be imported into Mechanical from multiple systems. It is possible to combine composite shell, composite solid, and non-layered shell and solid meshes to perform mixed analysis. Mechanical does not allow overlap of node/element number from multiple systems; therefore, the import fails if the meshes from different systems are overlapping in node/element numbers. Meshes from upstream to downstream Mechanical Models are renumbered automatically to avoid any overlap. For every analysis system (mesh), you have the choice between automatic renumbering (default) and manual configuration. If automatic renumbering is disabled, you must ensure that the element/node numbering is unique for each mesh. In this tutorial, first we will model Composite pressure vessel in ACP then we will model metal parts in mechanical model and at the we will combine models in static structural.

**Agenda: **

• Solid modeling of composite vessel

• Add metal parts

• Transfer parts to ANSYS Mechanical

About the Instructor

Researcher at Lancaster University

I am a Mechanical Engineer with over 3 years’ professional experiences. I currently work as a researcher in Lancaster University . I finished my Master degree in the field of Mechanical Engineering at Kingston University (London) in 2016 and gained a distinction. I completed my Mechanical Engineering BSc at Azad University of QazvinIran in 2013.

I chose the subject of my MSc dissertation in a way that enabled me to work in experimental research and finite element analysis. Utilising all my experience and software expertise encouraged me to continue my research and dissertation in the field of composites. In my MSc project, critical buckling loads of laminated composite plates with different stacking sequences are determined through experimental and finite element method. The results from these two methods are compared and recommendation for replacing tests with modelling was made.

I have made these tutorials based on my knowledge that I got from my dissertation. This tutorial contains three main sections. The first section is dedicated to beginner who has never worked with Ansys software. In this section you will learn how to work with ANSYS software and also creating and analyzing simple composite model. In the second part of this tutorial you will develop knowledge to do eigenvalue, harmonic response and modal analysis in the ANSYS and also you will learn how to make sandwich composite model in ACP by using honeycomb core. In the last part of this tutorial, you will learn how to create complex geometry in ANSYS such as: lug, reinforced beam, pressure vessel, tensile test sample and modeling of delamination. Then you will learn how to do complex analysis by using more than one tools in project schematic such as delamination, tensile test, fatigue test, progressive damage and finding natural frequencies and mode shape of wing.
