RADIOSS Rate Dependent Foam Model with Unloading (Law 70)
Compressive experiments are carried out over a range of strain rates ranging into the high-speed impact regime. Tests include three stress-strain measurements in the .01-1 /s strain rate range, and two high-speed compressive stress-strain curves in the 10-100 /s range, covering a total strain rate range of five decades. A compression curve loaded to a strain just prior to densification is then unloaded. Poisson's ratio as well as one quasi-static tensile test are also provided for stability.

This model allows you to simulate both the loading and unloading behavior of a foam impact.
