The maximum operating stress is computed and limited to prevent conditions of ratchet(progressive plastic deformation with cycles), and not to fatigue.

也有一个对最大组合应力的限制，持续负载加上位移应力，以限制渐变。

The results indicate that the elastic operating stress range of a torsional axis is extended greatly by pre-twist process and the main reason lies on surface residual stress.

结果表明，预扭后扭力轴弹性工作应力范围得到极大扩展，其主要原因在于预扭塑变形成的表面残馀应力。

I want to stress that this in no way reflects on the operating performance or financial integrity of HP.

此外，我想再次重申，我的离任不会对公司运营表现及金融体系造成影响。
