The paper deals with complex nonlinear time-dependent material models used in a structure exposed to fast dynamic loading. The finite element solution with the use of the explicit method for the direct integration of equations of motion is provided. Two material models suitable for description of nonlinear response of structure to dynamic loading were developed. These models are based on combination of visco-elastic behavior with the visco-plastic or visco-damage behavior. Behavior of these two models is compared. The behavior of the models under the impact loading is different and the paper shows the results.
