An alternative approach for the analysis of flexible structure is presented. Instead of following theories of finite deformation, classical models with infinitesimal strain and engineering stress are assumed as the basis of formulation. A compatible description concept is developed to handle the large geometrical change due to load. Basic concepts are discussed in an accompanied article: ‘Analysis of the changing geometry of flexible structure: 1. Approach and formulation.’ A general procedure to formulate the flexible structural model is proposed. Following the procedure, an algorithm is formulated in this article to study three-dimensional flexible solids. Numerical results are obtained to verify the concept and procedure.

柔性结构几何变化分析：2.柔性实体分析

提出了一种用于分析柔性结构的替代方法。不是遵循有限变形理论，而是假设具有无穷小应变和工程应力的经典模型作为公式的基础。开发了一个兼容的描述概念来处理由于负载引起的大的几何变化。随附文章中讨论了基本概念：“柔性结构几何变化的分析：1. 方法和公式”。提出了制定柔性结构模型的一般程序。遵循该程序，本文制定了一种算法来研究三维柔性固体。获得了数值结果来验证概念和程序。
