結構完整性評估和大變形分析

內容概要

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家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面 的簡略總結。書中首次把有限元線法引入斷裂力學，推導建立了斷裂有限元線法，用于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）敘述了斷裂和有限元線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合評估結構完整性方面的研究成果；第二部分（第六、七章）介紹了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合的應用情況；第三部分（第八、九、十、十一和十二章）詳細提供了兩種大變形理論在某發(fā)動機飛輪圓盤分析評估中的應用，給出了爆炸強度和開裂屈服的計算方法，并與其他軟件進行了分析對比；第四部分（第十三章）初步分析了材料不連續(xù)屈服特性對結構失穩(wěn)和破壞的影響規(guī)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(yè)研究生的教學參考書。
