前言残余应力是当没有外力作用时物体内部保留的内应力。它是在构件所经历的工艺过程中形成的。它的存在会引起加工后零件变形和开裂等缺陷产生,而且对构件的疲劳破坏、应力腐蚀、脆性破坏及耐磨性和结构的静态动态强度稳定性也都有极大的影响。为了合理的调整
Foreword Residual stress is the internal stress that remains inside an object when there is no external force. It is formed in the process experienced by the component. Its existence will cause defects such as deformation and cracking of parts after machining, and also greatly affect the fatigue failure, stress corrosion, brittle failure and wear resistance of the components and the static stability of structure dynamic strength. In order to adjust reasonably
