Conference paper


The propagation of converging polygonal shocks was studied theoretically and numerically by Schwendeman and Whitham (1987)[1]. Using the approximate theory of geometrical shock dynamics (GSD), they found solutions of the behaviour of cylindrical polygonal shock waves. They showed that an initial polygonal shape repeats at different intervals during the converging process. We have conducted experiments creating similarly shaped shock waves and compared with their work.
