内容简介
船舶与海洋工程建造是个复杂的生产过程，制造（热加工）工艺伴随着船舶整个建造过程，制造（热加工）工艺力学行为引起的结构内部残余应力及变形对船舶制造质量具有重要的影响。而这些力学问题不仅与其它工程领域的力学问题不同，且与设计时考虑的力学问题也不相同，问题的性质及求解方法都有着其专业特殊性，解决这些力学问题对提高工艺水平和建造质量具有重要的意义。本书基于热弹塑性有限元分析法和固有变形理论，针对船舶与海洋工程建造过程中的热点和难点问题：弯板成型，船体构件、分段及总段焊接装配，高强度大厚度海洋平台桩腿板材切割等三个典型制造（热加工）工艺过程开展了力学行为研究，从力学的角度分析建造工艺的科学性和合理性，进而为施工工艺的改进和优化提供理论依据及数据支持。
