残余压应力 meaning in Chinese

rasidual compressive stress
residual compressive stress

There are three types of wrinkle which frequently occur in the sheet metal forming process : flange wrinkling , wall wrinkling , and elastic buckling of the undeformed area owing to residual elastic compressive stresses
在金属板料成型加工中通常存在三种类型的起皱现象：法兰起皱，侧壁起皱，和由于残余压应力在未变形区产生的弹性变形。
On basis of numerical simulation , the optimized weling technological has been vadidated and adjusted by plane test , results show that residual stress of both ends welded in advance can be decreased by the interspace welded later , and decreasing effect is the most obvious in the 50mm range of the interspace ; for local heating , it is 60mm from the edge of heated area to decrease residual stress
通过平板试验得到了分段焊与局部加热合理工艺参数,并在此基础上,对转轮的焊接残余应力场进行了调整与控制,使叶片出水边危险区域附近产生了较大的残余压应力,且转轮整体的残余应力水平低于转轮材料屈服极限的三分之一。
