[程序][科研][本构] BMMF: Bilinear Material Model Fitting Tool [BMMF:二折线试验滞回曲线本构拟合工具]

实干、实践、积累、思考、创新。


介绍一个科研小工具,网友让我写的一个辅助科研的小工具,用于研究材料本构参数及根据试验结果拟合材料参数。

  • 程序图标 ( Program Icon )

  • 程序介绍 ( Program Introduction)

基于 OpenSees Steel01材料 http://opensees.berkeley.edu/wiki/index.php/Steel01_Material进行二折线材料参数拟合的工具。

Bilinear Material Model Fitting Tool. Based on OpenSees Steel01 Mateiral.

用户可以导入参考滞回曲线,及参考位移历程,然后有针对的进行材料参数的拟合。

  • 程序界面 ( Program Interface )

  • 程序案例( Program Examples )

以下是一个试验滞回曲线。从图可以看出,这个滞回曲线是个近似的随动二折线滞回规则,且有明显的各向同性强化现象。

采用 BMMF 拟合一个不考虑各向同性强化仅仅是二折线及随动强化(without isotropic hardening, only bilinear and kinematic hardening)的材料本构。如下图:

bilinear and kinematic hardening without isotropic hardening

采用 BMMF 拟合一个不考虑各向同性强化仅仅是二折线及随动强化(with isotropic hardening, only bilinear and kinematic hardening)的材料本构。如下图:

拟合效果对比(Comparison):
