ANSYS Composite PrePost Material Properties Tutorial

Temperature-, Shear-, and Degradationdependent Material Properties

The user is familiar with
Standard workflow in ANSYS Workbench and ANSYS
Composite PrePost
Composite Solid Modeling
Basics of Composite Engineering

Account for the effect of
temperature,
shear due to ply-draping,
and material degradation due to manufacturing or other artifacts,
on your material elastic and strength properties.

Controllable material properties:
Isotropic and orthotropic elasticity
Orthotropic strain and stress limits
Puck constants

1. Define material property-dependencies in
Engineering Data
2. Set up analysis in Workbench
3. Define thermal condition
4. ACP-Pre
Perform draping analysis to assess ply-shearing
Define local material degradation based on a table
5. Perform analysis and postprocessing
Procedure

A simplified compressor blade under pressure and
rotational loading
The blade is made up of a fictitious laminate
Simple Example: Compressor Blade

Failure Analysis:Max Strain and Stress
Set up a Failure Criteria Definition with Max Strain and Stress, and create a
Failure Plot using this definition showing the results on the solid elements.

ANSYS Composite PrePost R16.0 provides the ability
to easily include elasticity and strength propertydependence of your material on
temperature, plyshearing, and degradation.
The procedure works for shell- and solid based
workflows.
The effects can be activated or deactivated
individually on material- and analysis-level.
The key-challenge is to identify the material
properties (elasticity and strengths) at different
operating points (materials testing).
