Description: CZone for Abaqus is an add-on product that combines the CZone methodology for composite crushing with the analysis capabilities of Abaqus/Explicit. This combination enables the inclusion of crushing behavior in FEA simulations of composite structures subjected to impact. The localized loading behavior in CZone for Abaqus is modeled using a surface-to-surface contact interaction.

The CZone for Abaqus functionality has been enhanced to provide a more integrated solution for composites crush simulations in Abaqus/Explicit. The enhancements include extended coverage of Abaqus functionality as well as significant improvements to the user interface and the execution process:

• Composite shell sections with orientations defined on individual layers or using distributions are now supported.

• Field variables are no longer needed to define and report the crushing contact state.

• New interface for the definition of the crush stress of the material.

• New interface for the definition of CZone crushing contact interactions.

• New output variable for CZone crushing state.

• Simplified execution process, without the need to use a precompiled Python script (fileReader.py) to run a CZone for Abaqus analysis.
