Debonding behavior of a double cantilever beam

This example examines the debonding behavior of a double cantilever beam.

The following Abaqus features are demonstrated:

  • predicting debond growth in a double cantilever beam (DCB) using crack propagation analysis with the VCCT fracture criterion, cohesive elements, and surface-based cohesive behavior in Abaqus/Standard;

  • demonstrating the use of contact clearance assignment between surfaces with the VCCT fracture criterion and surface-based cohesive behavior in Abaqus/Explicit to predict debond growth;

  • restricting delamination growth and predicting the onset of debonding in models without a predefined crack tip using cohesive elements to supplement the VCCT fracture criterion for modeling the Z-pins and stitches that are commonly used in aerospace applications; and

  • predicting progressive delamination growth at the interface in a double cantilever beam subjected to sub-critical cyclic loading using the fatigue crack growth criterion based on the Paris law.
