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).
