Abstract
Smoothed particle hydrodynamics (SPH) is extended to the strain rate independent elastic-plastic large deformation analysis for low velocity contact problems. The volume constant condition is imposed on the plastic deformation process using a pressure equation given by the particle density condition in a unit volume. Test problems show that these improvements lead to good stability and accuracy of large deformation analysis.
