Abstract:

The current work examines the effects of the adhesive layer by systematically varying the modulus in a thin layer of adhesive 0.40 mm and studying the effects on the field variables near the crack tip. The adhesive layers have moduli that vary from 0.7 to 41.4 MPa, so that a range of situations is considered from adhesives that are relatively weak to those that are comparable to the other two materials.
