FTMP場の理論に基づく変形-破壊遷移過程の表現とDI-CAPモデリング

抄録

A new scheme called Di-CAP (Deformation-induced Context-dependent Autonomic Pluripotency) modeling is proposed based on the flow-evolutionary law constructed within FTMP (Field Theory of Multiscale Plasticity). The scheme allows not only appropriate reproductions of deformation-induced inhomogeneities, but also flexible manipulations of them for further extended testing and/or restart analyses. The scheme is applied to a couple of problems to verify the concept. Demonstrated first are FTMP's basic capabilities in reproducing various dislocation patterns under typical loading modes. Secondly, the evolved substructures are shown to be freely manipulated via simple “cut-and-paste” operations. A systematic series of preliminary analyses on the reproduced models identified the critical pieces of information that must be transferred for the above purposes.
