Transformation Field Analysis

变换场分析（TRANSFORMATION field analysis，TFA）是一种新的非均质系统中相互作用的物理过程的分层建模方法。 研究，将提供以下新的理论结果和应用的TFA：（a）率形式的影响函数和控制方程，应用涉及的热弹性模量的相的变化。 (b)制定新的形状函数，用于局部非弹性变形场的细化;以及（c）：在TFA的背景下使用单胞模型，用于局部变形和损伤过程的精细分析。

TRANSFORMATION FIELD ANALYSISAbstractThe Transformation Field Analysis (TFA) is a new method for hierarchical modeling of many interacting physical processes in heterogeneous material systems. The research, will provide the following new theoretical results and applications of the TFA: (a) A rate form of the influence functions and governing equations, for applications involving changes in thermoelastic moduli of the phases. (b) Formulation of new shape functions for refinement of local inelastic deformation fields; and (c): Use of unit cell models in the context of the TFA, for refined analysis of local deformation and damage processes.
