As far as I am concerned ABAQUS considers viscosity effect on stress wave propagation in ABAQUS/Explicit by defining two parameters such as linear and quadratic bulk viscosity. By increasing viscosity, we get smooth stress propagation, but with energy dissipation. However, I am looking for a way to switch off viscosity effect and compare the results with analytical method in which pure elasticity is considered without any viscousity. Kindly let me know if you have any idea, Thanks in advance.
