We calculate a few numerical solutions of the focusing question related to different flare angle spherical surface piezoelectric ceramics ESWL shockwaves. To do so, we first calculate the actual dynamic focus of spherical surface shock waves near the center of a sphere launched by the spherical surface piezoelectricity ceramics (ESWL) by using a discrete form of the ChisnellChesterWhitham(CCW) beam method. The numerical results show a focusing characteristic of the shock waves near the spherical surface piezoelectricity ceramics EWSL's geometric center, namely near the center of a sphere. The actual dynamic focus is not the center of the sphere but was somewhat offset. The focusing energy and the pressure ratio in the axis increase as the angles increase.
