損傷現象を考慮した拡張下負荷面モデルによる弾塑性解析

抄録

The subloading surface model excluding a purely-elastic domain is capable of describing the cyclic loading behavior. The initial subloading surface model was extended to consider damage phenomenon to describe macroscopic softening behavior and degradation of Young's modulus by accumulation of microscopic damage. To describe the cyclic loading behavior more accurately, the extended subloading surface damage model is formulated introducing the damage effect that consider unilateral effect based on damage mechanics.We simulate elastoplastic damage behaviors of metal to assess availability proposed algorithm.
