APPLICATION OF INTEGRAL REPRESENTATIONS OF DISPLACEMENT POTENTIALS IN ELASTO-DYNAMICS.
NORTHROP CORP NEWBURY PARK CALIF VENTURA DIV
With the aid of a gauge condition analogous to the Coulomb gauge of electromagnetic theory, the integral form of the solutions of the three fundamental boundary value problems of elastodynamics are obtained. These solutions are given in terms of surface distributions of the displacement potentials and their derivatives, together with volume distributions of the body forces, and surface distributions of the applied stresses andor prescribed displacements. The integral representations are used to formulate sets of simultaneous integral equations whose solutions are the desired surface distributions of the displacement potentials. In addition to considering problems involving more than one media, this paper presents an extension of previous work available from OTS as UCRL-6779 which considered the corresponding two-dimensional problems.
