This paper analyzes the admissible stresses used to calculate the diamter of axles according to torsional stress and resultant stress, and some suggestions are given. 对按扭矩估算轴径和按弯扭合成力矩计算转轴轴径公式中的许用应力进行了分析,给出了修正意见。
The resultant tensile stress in the matrix around the larger pores may induce the cracking of the pore wall. 孔隙中的压力所导致的周围孔壁中的拉应力可能引起基体开裂。
The resultant stress includes not only the normal stress on the fault plane but also the shear stress on the fault plane, by which the description of stress field is more effective than by single stress. 合应力Sr中既包括了作用在断层面上的正应力,又包括了断层面上的剪应力,它比单独用一个应力描述应力场更有效。
The resultant stress will exceed the tensile strength of the material, and caused the brittle cracking. 模具在进行第二次线切割时表面产生的附加拉应力与材料已存在的内应力相叠加,其总应力超过了材料的抗拉强度,导致裂纹沿碳化物脆性开裂。
The generalized constitutive relations of resultant stress and resultant moment with strains of piezoelectric laminated plate, which are nonlinear with respect to electric field, are obtained from nonlinear piezoelectric equations and geometric equations. 从非线性压电方程和几何方程导出了压电层合板合应力、合力矩与应变之间的广义本构关系,这些关系关于电场是非线性的。
In the calculation of wall structures of silos, the designers do not take into consideration the longitudinal curvature of a silo viewed as a whole and the effect of the resultant curvature stress on the circular stress. 圆筒仓设计时,在简壁结构计算中,不考虑整体圆筒仓的纵向弯曲,及由此所产生的弯曲应力对圆筒仓环向应力的影响。
In addition, we also drawed resultant fatigue life curve and expression which were characterized by total strain and pseudo& stress for these materials, discussed the relationship between initial cracking life versus failure life of the tests, and proposed empirical formula. 文中还给出了分别用应变和虚拟应力表示的三种材料的综合疲劳寿命曲线和表达式。此外,还对裂纹起始寿命和失效寿命间的关系进行了探讨,并给出了经验关系式。
When the superconductor subjected merely to tensile stress, the stress intensity factor decreases when increasing the crack length because the resultant force always has dominant effect on the stress intensity factor. 当外磁场较小超导体内只受到拉应力时,应力强度因子随裂纹长度增大一直减小,合力始终对应力强度因子起着决定影响。
Then get the distribution rules of resultant displacement, shear stress and equivalent stress and get the positions where cracks easily generate on the six kinds of models of mortar. 然后确定合位移、剪切应力和等效应力的分布规律,找出六种模型砂浆层容易出现裂缝的位置。
