The nonhomogeneous elastodynamics problem

  • Published:
Journal of Engineering Mathematics Aims and scope Submit manuscript

Summary

The solutions of nonhomogeneous boundary value problems which arise from the study of the dynamics of bounded, elastic solids are represented by the superposition of two components: (a) a “quasi-static” solution which satisfies the nonhomogeneous boundary conditions, and (b) an eigenfunction expansion which satisfies the corresponding homogeneous boundary conditions. The method obviates the frequently used but often cumbersome technique of integral transforms, and a resolution of the problem is achieved by the use of classical mathematical analysis. The general theory developed is illustrated by considering the problem of point symmetric motion of a suddenly loaded spherical shell for which a complete solution is presented.
