Summary

A discontinuity of the in-plane displacements and slopes in an infinitely extended anisotropic laminate is considered under coupled bending and stretching. The laminate is supposed to the thin with arbitrary anisotropy of the constitutive plies. Using the classical 2-D theory of laminates and techniques of complex potentials, a family of exact solutions is obtained for the case of a static problem. As it follows from the analysis, the energy of dislocations does not depend on their orientation. A few numerical results for real laminates are considered.
