K-0514 結晶すべりモデルを用いた塑性変形と粒子すべりモデルを用いた超塑性挙動の検討(S04-1 微視組織と変形・接続信頼性)(S04 金属材料の組織と疲労強度信頼性)

Abstract

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.
