Abaqus Rate Dependent Viscoplastic (*RATE DEPENDENT)
Tensile 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 tensile stress-strain curves in the 10-100 /s range covering a total strain rate range of five decades. Poisson's ratio is provided. Material model calibration is provided either to *ELASTIC followed by *PLASTIC,RATE or *PLASTIC, *RATE DEPENDENCY.
Please note that requesting strain rates that would produce test speeds below 1 mm/min may result in additional charges.

Temperature dependence can also be incorporated into this model by ordering the model at multiple temperatures.

This model is used in crash, drop testing and impact explicit simulations. It is used to introduce strain rate dependence into the material model.
