Crack path selection in mixed mode fracture tests of adhesive bonds, including those with locally weakened interfaces

Crack path selection in mixed mode fracture tests of adhesive bonds, including those with locally weakened interfaces Adhesives offer many advantages over discrete mechanical fasteners such as bolts and rivets. By eliminating the holes or other mechanical fasteners, components may often be made thinner that will save weight, time, and costs. Because adhesives are often applied continuously and efficiently with robots, they can seal out corrosive liquids such as saltwater to improve structural durability, and significantly improve the torsional and bending stiffness of parts in automobiles.
