Stress 分两种,一种是direct stress,另一种是shear stress 在两端的pure bending moment作用下beam的截面可产生Direct stress,而在shear loading的作用下截面会产生shear stress,两者均有随截面深度变化的图像(横轴即为截面的neutral axis) Shear stress in cross-section的计算公式是T(y)=SA'yo/Ib, 式子中的S...

shear and bending moments. We designed sections based on bending stresses, since this stress dominates beam behavior. There can be shear stresses horizontally within a beam member. It can be shown that vertical horizontal f f = θ R L = ...
Bending stress is a normal stress acting across and through the beam's cross-section caused by the beam's bending. On the other hand, shear stress is brought about by the forces that cause vertical tearing of the beam along the beam's cross-section. ...

A primary stress is a principal stress, shear stress, or bending stress generated by imposed loadings that are necessary to satisfy the simple laws of equilibrium or internal and external forces and moments. From: Surface Production Operations, 2016 ...
