Tutorial 4 - Cohesive Functionality

Tutorial 4 demonstrates the use of the cohesive functionality in Simulation Composite Analysis. View input file requirements for using this cohesive functionality and use Abaqus/CAE to build the input file.

Topics in this section

Introduction
Create the Part
Defining the part geometry is generally the first step in the development of a finite element model.
Define the Ply Material
Define the linear elastic material for the ply section.
Create a User Material with the Create Cohesive Material Plug-in.
The Create Cohesive Material plug-in defines the complete material response for a Simulation Composite Analysis cohesive material.
Create the Sections
After the part and the materials have been created, sections for the ply and cohesive cells need to be defined and assigned.
Define an Assembly
In order to apply boundary conditions, loads, etc., an instance of the part must be added to the assembly.
Create an Analysis Step and Define Solution Controls
Define a step allowing boundary conditions and output requests to be added to the model.
Define Field Output Requests
In order to use Abaqus Viewer to examine the cohesive material damage information generated by Simulation Composite Analysis (such as the damage state and failure index), you must request that state variables (SDV) be printed in the Abaqus output (.odb) file.
Mesh the Part
Create the mesh on the part geometry.
Apply Boundary Conditions
Create a boundary condition that fixes one end of the beam.
Define the Load
To apply a pure mode I loading to the beam, vertical displacements are applied to the free end.
Submit the Analysis
The model is finished and is ready to be solved.
View and Interpret Results
View the state variable outputs from Simulation Composite Analysis that are stored in the output database file.
Required Input File Keywords
Modify legacy input file keywords for use with new technologies.
Summary
This tutorial demonstrated the use of Abaqus/CAE in creating a double cantilever beam which was analyzed using the cohesive functionality in Simulation Composite Analysis.
