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
• Define draping based on an oriented selection set
• The effect of different seed points

Selection Rules allow you to select elements through geometrical operations. Thes selections can be combined with Oriented Selection Sets or Modeling Plies to define plies of arbitrary shape. This feature can be used to define local reinforcements (patches) or staggering. In this tutorial, first we are modeling tube geometry in CAD software then we will import PARASOLID format file into ANSYS geometry. Then we will apply mesh and create name selection. In the last step in ACP we are going to have introduction of rules command in ACP and we will see its usage and application in the software.

Agenda

•  Introduction to rules
• Using Parallel rules
• Using a tube rule following an edge
• Using a tube rule and parallel rule at same time
• Using a template rule

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

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

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

• Transient Structural
• Steady-State Thermal
• Transient Thermal

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.

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

With ANSYS ACT, you can create a customized simulation environment that enables your engineering team to capture and use expert knowledge, specialized processes, and best practices, improving productivity, efficiency and effectiveness. The software enables you to encapsulate APDL scripts, create custom menus and buttons to incorporate your company’s engineering knowledge, embed third-party applications, and create your own tools to manipulate simulation data. In This tutorial you will learn how to use ACT in ANSYS software. First, we need to download HONEYCOMBCREATOR extension from ANSYS application store. Then we will install extension. Then we will create shell model of honeycomb in design modeler.

Honeycomb structures are natural or man-made structures that have the geometry of a honeycomb to allow the minimization of the amount of used material to reach minimal weight and minimal material cost. The geometry of honeycomb structures can vary widely but the common feature of all such structures is an array of hollow cells formed between thin vertical walls. In this tutorial we are going to create sandwich composite plate. First, we will create two composite plates in two different ACP and then we will create honeycomb in mechanical model by using Honeycombcreator extension. Then, we will combine three models into static structural to do stress analysis. At the end we will do eigenvalue simulation. 

Agenda:

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

Solid model settings control how the solid model is divided into elements in the thickness direction and how drop- and cut-off elements are handled. The level of detail required in the solid model depends on how accurate certain features are to be modeled. This depends on the judgment of the designer. Extrusion guides add more complex possibilities in shaping the model. The cut-off operation is analogous to machining a composite part after curing. In this tutorial we are going to use extrusion guide, cut off element and snap to geometry to create complex geometry.
