等価介在物法を用いた逆解析の不均一・非弾性材料制御への応用にむけて

抄録

The inverse analysis scheme based on equivalent inclusion method, which makes possible to obtain stress field from displacement field and boundary condition, even if its constitutive relationship is unknown, was developed. For the material control purpose, displacement can be measured remotely, however, it is difficult to obtain stress field especially if constitutive relationship is unknown, material is inhomogeneous, or inelastic. In this paper, the formulation and result for plain strain inelastic deformation, and the formulation for thin plate bending are shown. The new material control scheme, which is based on not only displacement field but also stress field, is also proposed.
