| Abstract: | One dimensional elastic plastic strain waves induced by impulsive stress loading are simulated numerically by corrected smoothed particle hydrodynamics. In order to study the effects to control the numerical noise occurred at the shock front, both the artificial viscosity and flux corrected transport methods are used and compared in the numerical examples. The results show that good accuracy in the numerical simulations of stress waves can be obtained by corrected smoothed particle hydruodynamics. |
