材料性能的建模方法

Modeling Method for Material Behavior

提出一种用非线性函数的线性组合来预测材料性能的建模方法.在叙述其数学原理后,给出了确定参量的数学方法,同时给出5个实例的建模结果.得到的计算结果与理论符合良好,在一定程度上可以预测出材料性能.讨论了多元函数的建模.

A modeling method of predicting material behavior by the linear combination of nonlinear functions is proposed. On the basis of analyzing its mathematical principle, the mathematical methods to decide parameters are given. Otherwise, the modeling results of five practical examples are shown. The experimental data are in good agreement with the theoretical calculation. Therefore the model can, to some extent, predict the material behavior. The modeling of multivariate function is also discussed .
