摘要

A uniqueness theorem for the weak solution of an initial-boundary value problem in the anisotropic elasticity theory with the boundary conditions that "do not conserve" energy, namely, with the impedance and inertial type conditions is proved. The chosen method of proof does not require the positive definiteness of the elastic constant tensor (the case that may arise when solving the problems by the homogenization method for composite materials), but it requires to take the energy variation law as a postulate.
