結構完整性評估和大變形分析一直是土木、機械和力學及其航空航天領域專傢學者研究的重要課題。本書是作者通過多年研究工作在結構非破壞性評估和結構大變形計算分析方麵 的簡略總結。書中首次把有限元綫法引入斷裂力學，推導建立瞭斷裂有限元綫法，用於結構的完整性分析和評估。全書分為四部分：第一部分（第一、二、三、四和五章）敘述瞭斷裂和有限元綫法及其在機翼開裂分析中的應用以及與一階可靠性法相結閤評估結構完整性方麵的研究成果；第二部分（第六、七章）介紹瞭最新超聲波檢測結構疲勞裂縫技術以及定量非破壞性評估技術與概率可靠性方法相結閤的應用情況；第三部分（第八、九、十、十一和十二章）詳細提供瞭兩種大變形理論在某發動機飛輪圓盤分析評估中的應用，給齣瞭爆炸強度和開裂屈服的計算方法，並與其他軟件進行瞭分析對比；第四部分（第十三章）初步分析瞭材料不連續屈服特性對結構失穩和破壞的影響規律。

本書可供有關科研、設計和工程單位的科技工作者參考，也可作為高等院校土木、水利、力學及其機械類專業研究生的教學參考書。
