FEpX是用于计算多晶固体的弹塑性变形的建模框架。使用该框架，可以模拟晶体聚集体（称为虚拟多晶体）在大应变变形路径上的力学行为。本文介绍了理论，有限元公式，并共同定义建模框架的数值实现的重要功能。本文还提供了几个模拟多晶固体弹塑性行为的例子来说明框架的可能应用。有一个相关的有限元代码，也称为FEpX，它基于这里提出的框架，并用于执行示例中提出的模拟。这篇文章为使用该代码的用户提供了建模框架的可引用参考。有关输入和输出数据的格式、代码体系结构和代码归档的具体信息包含在其他文档中。
FEpX is a modeling framework for computing the elastoplastic deformations of polycrystalline solids. Using the framework, one can simulate the mechanical behavior of aggregates of crystals, referred to as virtual polycrystals, over large strain deformation paths. This article presents the theory, the finite element formulation, and important features of the numerical implementation that collectively define the modeling framework. The article also provides several examples of simulating the elastoplastic behavior of polycrystalline solids to illustrate possible applications of the framework. There is an associated finite element code, also referred to as FEpX, that is based on the framework presented here and was used to perform the simulations presented in the examples. The article serves as a citable reference for the modeling framework for users of that code. Specific information about the formats of the input and output data, the code architecture, and the code archive are contained in other documents.
