Original Abstract
The contribution describes a study of the behaviour of a crack growing in a layered composite material and penetrating through an interface from one layer into a second one. Special attention is devoted to a crack touching the interface. Conditions for the stability of a crack terminating at the interface between two materials are analyzed. The problem is studied under the assumptions of linear-elastic fracture mechanics. A new tentative criterion of stability based on application of the strain energy density concept is formulated and applied to the problem. The criterion of stability formulated is based on application of the strain energy density concept as originally formulated by Sih for cracks in homogeneous materials.
