The condition of uniaxial stress is closely approximated in prismatic bars subjected to pure axial tensile or compressive ioading. 承受单纯轴向拉伸和压缩的棱柱杆十分近似地处于单轴的应力状态。
The presence of the greater resid-ual tensile stress induces the stress corrosion cracking in the course of the acid pickling. 其原因是磁屏表面存在较大的切向拉应力，从而在酸洗过程中产生了应力腐蚀开裂。
