NPO活動による超弾性・ダメージ・粘弾性構成則の汎用FEMコードへの組込み開発および公開

It is important to select appropriate material model for non-linear CAE. However, the models provided in commercial software are limited. In addition, it is not efficient to implement the specific material models to many commercial FEM codes individually. In the activity of sub committees in the Nonlinear CAE Association (JANCAE), we have developed hyperelastic, damage, and viscoelastic constitutive laws using user subroutines to be incorporated into commercial FEM codes. The developed subroutines, called Unified Material Model Driver for rubber (UMMDr), have recently been released to the public. This paper presents an overview of the subroutines and examples of their use.
