A crack at the interface of anisotropic bodies. Singularities of the elastic fields and a criterion for fracture when the crack surfaces are in contact

Interface tunnel cracks in a composite anisotropic space

“…8,9 Consider a special case of the problem. Suppose the surfaces of one crack (r = 1, l 0 = (−a, a)) are loaded with a constant symmetrical load − * = 0, + * = 2{Q j } 3 .…”

“…3-7), but only qualitative results are known in the most general formulation for an anisotropic space. 8,9 1. Formulation of the problem and reduction of the problem to a Riemann matrix problem in S (R 2 ) Suppose a space, consisting of two dissimilar anisotropic half-spaces, incompletely coupled in the x = 0 plane, is in a two-dimensional stress-strain state (without planes of elastic symmetry 10 ).…”
