热变形的固有应变预测法及实例

A method to predict residual distortion based on inherent strain and its application to heating processes

    摘要
  • 摘要: 阐述了以固有应变为基础的弹性板单元有限元残余变形预测法。通过金属结构的焊接变形的预测和船板的线状加热弯曲成形变形计算的实例,验证了固有应变为基础的弹性板单元有限元残余变形预测法在热加工过程中应用的可行性。

     

    Abstract: A method to predict residual deformation based on inherent strain was introduced.The proposed method was applied to predict welding deformation for the tank with lower temperature and plate bending deformation by line heating.Feasibility of the proposed method was also verified.
