 # composite:shear\_crimping\_operator

 Last update: 31.07.2026 

**Version: 0.0.0**

## Description

Computes shear crimping criterion for layered elements. Use the composite::layup\_provider\_operator to import the required lay-up data. The criterion can also be used for stack of solid elements if the ACP's composite definition file of the solid model was loaded by the composite::layup\_provider\_operator. Elements without section data are skipped.
