Geometry and Material Property (Part-1)15:51
This is a popular test in order to determine mode I fracture energy of adhesive bonds, which is a measurement of the fracture toughness in the presence of pre-crack.
Agenda:

Modelling Double Cantilever Beam

Creating Cohesive Mesh
Plotting Load-Displacement Curve
Assembly, Boundary condition and contact (Part-2)6:23
Mesh and plotting load displacement curve (Part-3)9:59

Geometry and the property of material (Part-1)9:58
Adhesive joints attract more attention due to their advantage of enabling the development of lightweight, cost-effective and highly integrated structures with a more uniform load distribution and improved damage tolerance. The SLJ has been the most studied in literature, on experimental and theoretical terms, due to its facilitated fabrication. But that does not mean the tensions present in the joint are easy to analyse.The aerospace area was the first sector that promoted the use of adhesives in the aircraft manufacturing process, due to its outstanding advantages over traditional methods such as welding or bolting. many types of commercial aircrafts whose economical operations benefit considerably from the reduced weight offered by the bonded composite assemblies.

Hyper-elastic properties of flexible adhesive12:33
Hyper-elastic materials are designed for modelling rubber or rubber-like materials in which the elastic deformation can be extremely large. These materials use something called a strain energy density function to derive the relationship between stress and strain. This allows them to model the relationship between stress and strain accurately even when the strain is between 100% to 700%, depending on the exact hyper-elastic model that is used.
Agenda
Using experimental data to find hyper-elastic properties of the material
Evaluating the hyper-elastic properties of the material

Trapezoidal traction separation law for flexible adhesive31:45
In this tutorial, we will use the same model as the previous tutorial but instead of using linear traction-separation law, we will use trapezoidal traction-separation law.
Agenda
Using trapezoidal traction separation law
Using provided trapezoidal traction law calculator

Geometry and Material Property (Part-1)5:59
Buckling is characterized by a sudden sideways deflection of a structural member. This may occur even though the stresses that develop in the structure are well below those needed to cause failure of the material of which the structure is composed.

Description

Welcome to the Adhesive Joints and Composite Material Abaqus Tutorial, the only course you need to learn how to model adhesively bonded joint and composite material in Abaqus software. This course is specially designed for mechanical, civil engineering students or engineers who want to expand their finite element knowledge. This course will teach you the theory behind input parameters as well as modelling and analysing the results.

** This project is intended for individuals who already have a basic understanding of Abaqus and are interested in learning about adhesives and composites. If you’re new to Abaqus, please refer to my beginner course to get started.

What you will get in this course:

**This Course is divided into 8 sections, I try to teach you sth new in each section. So, in order to get the most advantage of it, I highly recommend you to follow the course in order as the basic terms have been only explained in the initial sections.

Section 1: 2D adhesively bonded DCB (cohesive element)

In this section, you will learn how to model two dimensional double cantilever beam (DCB) using the cohesive element method.

Section 2: 2D Adhesively bonded SLJ (Surface-Based Cohesive)

In this section, you will learn how to model a two-dimensional Single-lap joint using a surface-based cohesive zone.

Section 3: 3D adhesively bonded DCB (Cohesive element)

In this section, you will how model three dimensional double cantilever beam using cohesive element method.

Section 4: 2D adhesively bonded DCB (XFEM method)

In this section, you will become familiarize with eXtended finite element method (XFEM) to model two dimensional double cantilever beam.

Section 5: 2D adhesively bonded ENF (XFEM method)

In this section, you will learn how to model two dimensional end notched flexure beam using eXtended finite element method.

Section 6: 2D adhesively bonded ENF (Cohesive element method)

In this section, you will learn how to model two dimensional end notched flexure using cohesive element method.

Section 7: Flexible adhesive (New Update May 2020)

This is a new section is that I added to this course in May 2020, This section will help you to learn how to model flexible adhesive in Abaqus software. The following subjects will be discussed in this section: Hyper-elastic properties of flexible adhesive, Bulk flexible Specimen, Single-lap joint with flexible adhesive, Trapezoidal traction separation law for flexible adhesive.

Section 8: Buckling and Post Buckling of Composite Plate

This section will help you to learn how to composite plate and analyse buckling and post-buckling condition on the plate.

Future updates:
Composite tube under crushing compression loading, Composite plate under 3 point bending, Composite panel under impact loading, 3D composite single lap joint (Estimated new update January 2021).

I hope you all enjoy these tutorials. Please send me a message if you think anything can improve the quality of this course as I am updating the course regularly.

Many thanks
