The shear stress criterion predicts failure caused by the interlaminar shear stresses and . The allowable limit is typically determined by a tensile lap shear test (lap shear strength).
Notes
Note that:
The listed failure criteria can be activated via the application menu (Tools - Preferences - ACP - Add-Ons - Adhesive Failure Criteria).
If both the peel and shear stress criteria are active, then the weighting factor can be used in one of the criteria in order to adjust because the peel and shear strengths typically differ.
Limitations
Review the following limitations:
Failure mode labels are not currently exposed and display "na" (not available).
Adhesive failure criteria are not currently exposed in Mechanical.
