L. Jentsch et D. Natroshvili, NONCLASSICAL INTERFACE PROBLEMS FOR PIECEWISE HOMOGENEOUS ANISOTROPICELASTIC BODIES, Mathematical methods in the applied sciences, 18(1), 1995, pp. 27-49
Two non-classical model interface problems for piecewise homogeneous a
nisotropic bodies are studied. In both problems on the contact surface
jumps of the normal components of displacement and stress vectors are
given. In addition, in the first problem (Problem H) the tangent comp
onents of the displacement vectors are given from both sides of the co
ntact surface, while in the second one (Problem G) the tangent compone
nts of the stress vectors are prescribed on the same surface. The exis
tence and uniqueness theorems are proved by means of the boundary inte
gral equation method, and representations of solutions by single layer
potentials are established. In the investigation the general approach
of regularization of the first kind of integral equations is worked o
ut for the case of two-dimensional closed smooth manifolds. An equival
ent global regularizer operator is constructed explicitly in the form
of a singular integro-differential operator.
