这是全英文版本。它是作者通过多年研究工作在结构非破坏性评估和结构大变形计算分析方面的简略总结。书中首次把有限元线法引入断裂力学，推导建立了断裂有限元线法，用于结构的完整性分析和评估。该书不仅可供有关科研、设计和工程单位的科技工作者参考，也可作为高等院校土木、水利、力学及其机械类专业研究生的教学参考书。

结构完整性评估和大变形分析一直是土木、机械和力学及其航空航大领域专家学者研充的重要课题。本书是作者通过多年研究工作在结构非破坏性评估和结构大变形计算分析方面的简略总结。书中首次把有限元线法引入断裂力学，推导建立了断裂有限元线法，用于结构的完整性分析和评估。全书分为四部分：第一部分(第一、二、三、四和五章)叙述了断裂有限元线法及其在机翼开裂分析中的应用以及与一阶可靠性法相结合评估结构完整性方面的研究成果；第二部分(第六、七章)介绍了最新超声波检测结构疲劳裂缝技术以及定量非破坏性评估技术与概率可靠性方法相结合的应用情况；第三部分(第八、九、十、十一和十二章)详细提供了两种大变形理论在某发动机飞轮圆盘分忻坪估中的心川。给出了爆炸强度和开裂屈服的计算方法，并与其他软件进行了分析对比；第四部分(第十—章)初步分析了材料不连续屈服特性对结构失稳和破坏的影响规律。

本书可供有关科研、设计和丁程单位的科技工作者参考，也可作为高等院校土木、水利、力学及其机械类专业研究生的教学参考书。

本书由南京水利科学研究院号著出版基金资助出版。
