Insert a layer of cohesive elements to simulate the effects of delamination.
- Type EMODIF, ALL, MAT, 1 into the command window to assign the ply material to all elements.
- Type CZMESH, , , 11, Z, 0.5 into the command window to create a layer of cohesive elements in the middle of our beam (z = 0.5 mm). The Graphics Window should appear as shown below.
The CZMESH command creates a layer of cohesive elements with zero thickness. These elements use the INTER 205 element defined earlier. The cohesive elements use the Simulation Composite Analysis cohesive material defined with the Create Cohesive Material tool.
Refer to the ANSYS APDL documentation for additional details on the EMODIF and CZMESH commands.
