...封装外围角点处焊点剥离应力最大,位于焊点靠近封装一侧,表明靠近封装一侧焊点部位容易开裂失效;以最大的剥离应力(peeling stress)作为跌落碰撞底焊点的失效准则,用Power原理建立的寿命预测模型,计算得到两种无铅焊料Sn3.0Ag0.5Cu和Sn3.5Ag的平均碰撞寿命分别为...

It is advised that the anchorage length of CFS, peeling stress, the strain of CFS under the ultimate load and the shear capacity should also be verified to insure enough ductility of the member.
文中还提出了应对碳纤维布锚固长度、剥离应力、极限状态下碳纤维布的应变、强剪弱弯等进行验算的建议。
Due to the above mentioned defects, early fatigue peeling occurs under the condition of overly contact stress at the top of the tooth caused by abnormal contact at the tooth surface.
因此，在齿面非正常接触导致齿顶接触应力过大的情况下，该齿轮发生了早期疲劳剥落。
The wear mechanism of high vanadium high-speed steel is combined micro-cutting and fatigue wear with carbide particle breaking and peeling off under stress.
