418 粒子すべりモデルを用いた構成則による超塑性材料の軸圧縮/引き張り(OS3-3 構成式(1))(OS3 機械材料の変形とそのモデリング)  [in Japanese] 418 Uniaxial tension/compression of superplastic material behavior described by particle sliding constitutive law  [in Japanese]

Meso-mechanical material modeling of super plastic metal alloy is attempted. Multi-crystal grains in the metal that exibit extensive surface sliding is modeled by setting a tangential spring layer between the grain and the matrix. The constitutive law for the domain in which mult-phase crystal grains of the type are dispersed is derived with the use of equivalent inclusion method on the basis of self-consistent shceme.
