Although the EPRI give a set of the approximate engineering solution method, actually the crack of parts in engineering project mostly presents inner 3D effect. If using 2D elastic-plastic or 3D elastic analysis, the result can't be precise. Because these methods have neglected the reassignation of the stress and strain which happened at nearly the top of cracks, carrying on 3D elastic-plastic analysis and J-integral calculation become the foundational work to study the expander and safety assessment of the pressure vessel cracks.

虽然EPRI给出了一套近似的工程解法，但实际上工程中构件的裂纹大多呈现内在的三维效应，若使用二维弹塑性或三维弹性分析必然不够精确，因为对裂纹的&等效&二维表达忽视了发生在靠近裂纹端部的应力和应变的再分配，所以对压力容器裂纹进行三维弹塑性分析及其J积分是研究压力容器裂纹扩展和安全评定的基础工作之一。
