摘要：

This paper considers the effects of artificial viscosity for Smooth Particle Hydrodynamics (SPH) computations. Results are presented for five different problems that each uses six different varieties of artificial viscosity. The results for some of the problems are significantly affected by the artificial viscosity. Copyright (C) 1996 Published by Elsevier Science Ltd.
