Propagation of finite amplitude waves in elastic solids

摘要: This thesis is devoted to consideration of finite amplitude waves propagating into an elastic half-space in a direction normal the boundary. Excitation by means strains applied at boundary as step functions time. The solutions obtained are combinations centered simple and shock waves. Longitudinal may appear alone but with transverse displacement components always accompanied longitudinal The foregoing discussed general illustrated example problem involving special nonlinear, compressible, hyperelastic material. A perturbation method, based on use characteristic coordinates, which facilitates approximate solution for arbitrarily prescribed strain conditions described.
