Abstract
In previous studies, we proposed a variety of models of material and methods for identifying the parameters of these models by multi-intensity impact test. In particular, the exponential model (Kobayashi & Yukawa, 1998) shows excellent accuracy in identifying the properties of material behavior. Although other papers reveal that this model is applicable in cases of varying impact duration and various temperatures, we have not yet discussed how the properties would change as the impact area changed. The purpose of this study is to propose an identification technique of nonlinear Voigt model with hysteresis and dependence on impact area by multi-intensity multi-area impact test. The nonlinear elastic element of this model is expressed by the exponential function based on displacement and impact area. And the nonlinear viscous element of the model is expressed by the product of the exponential function based on displacement and the exponential function based on velocity.
