STRAIGHT EDGE DISLOCATION IN A THIN 2-PHASE PLATE .1. ELASTIC STRESS-FIELDS

The solution of the boundary value problem in the theory of elasticity for straight edge dislocations placed parallel to interfaces in thin two-phase different-modulus plates is received for the first time with the aid of the modernized method of the surface virtual dislocations. The fields of the elastic stresses are calculated. It is shown that several components of the stress fields decrease along the plate with oscillations. The elastic fields found may be used as a basis for the solution of a wide class of the boundary value problems in the theory of defects.
