约束扭转 meaning in English

restrained torsion

Constrained twisting deformation
约束扭转变形
As a result , it is suggested that distortion should be taken into account to calculate the thin - walled bar with restrained torsion
因此建议，对薄壁杆件作约束扭转分析时一定要考虑截面畸变的影响。
Because of its simplicity of the critical moment and the good precision , the solutions based on gjelsvik theory are used in the elastic - plastic phase . the ultimate load carrying capacity of box section beams are calculated considering the effect of plasticity and residual stresses
其次，运用基于gielsvik约束扭转理论推导了箱形偏压杆的弹性弯扭屈曲荷载，同时给出了压弯杆在弹性弯扭屈曲的轴力和弯矩相关关系。
First , the stability of box section beams under pure bending is studied based on two different torsion theories on members with closed cross - section by umansky and gjelsvik in the elastic phase , and the critical moments are obtained . comparisons show that these two different theories give nearly the same critical moments
文章首先对箱形梁进行研究，分别基于umansky约束扭转理论和gielsvik约束扭转理论推导了箱形梁在纯弯作用下的弹性临界弯矩，并进行了比较，发现基于gielsvik约束扭转理论的临界弯矩具有较好的精度且形式简单。
