Transformation Field Analysis

摘要变换场分析（TFA）是一种对非均质材料系统中相互作用的物理过程进行分层建模的新方法。这项研究将提供以下新的理论结果和TFA的应用：(a)影响函数和控制方程的速率形式，用于涉及相的热弹性模量变化的应用。(b)拟定新的形状函数以细化局部非弹性变形场；(c)：在TFA背景下使用单元模型，对局部变形和损伤过程进行精细分析。

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.
