Uniform torsion embrace cross-sectional shear stresses whereas warping torsion embrace shear and normal (out of plane) stresses.
EK483
The principle of effective stresses applies only to normal stresses and not to shear stresses.
EK77
When the deflections of the plates middle plane is small compared with the thickness it can be assumed that: There is no deformation in the middle plane. The normals of […]
EK34
The principal stresses are the normal stresses acting on the planes with no shear stress.
