Stress waves induced in elastic solid models by shock waves were studied experimentally and theoretically. For shock-tube experiments, several kinds of solid models were made of transparent acrylic resin and shock waves at approximately Mach 3 were propagated to the models in stationary argon. The schlieren method with a spark light source were employed to visualize shock waves outside and stress waves inside the model. In the schlieren snap-shot photographs, not only shock waves around the models but also stress waves inside the models were observed. Numerical simulations were carried out for shock waves as well as stress waves employing the finite volume method based on the Godunov algorithm. Good agreement was obtained between the experiments and the simulations.
