The method for evaluation of Young's modulus through transient response was proposed in the previous paper. Although it approximated well for the case of a small temperature change, it did not for a highly nonlinear system with a large temperature change. The direct description method of temperature dependence of Young's modulus at prescribed points instead of a polynomial approximation method was applied to the evaluation method in order to improve the sensitivity of optimization variables to the objective function. It was found that the temperature dependence of a plastic material was well aproximated even for a highly nonlinear system. Increasing in the number of divisions improves the accuracy of the approximation, but at the same time degrades the convergency of the optimization. The optimum number of divisions was found to be in the renge of 5 to 7.
