초탄성 재료의 해석 정확도 향상을 위한 해석기법 고찰

Abstract

The hyper-elastic material which is used in various fields, has non-linear and large deformation characteristics. This characteristic of hyper-elastic material is represented by various nonlinear material model based on strain energy density function. In order to improve accuracy of hyper-elastic model analysis, the selection of suitable nonlinear material model is important. In this study, Tensile test and nonlinear analysis was performed for two type specimens and the possibility of nonlinear material model application is examined with respect to two specimens
