Webgeneral primary membrane stress to less than or equal to two-thirds of the material yield stress. Due to the margin between first yield and limit collapse for primary membrane plus bending stress, the stress limit for this category is set at 1.5S. Thus the allowable value of membrane plus bending stress is less than or WebAs a result, we can define the effective stress for von Mises theory to be equivalent to Eq. 6. 1 222 2 122331 s H =(s−s)+(s−s)+−()ss (7) 1 For dilation, stresses are the same in all directions and there is no shear. For distortion, stresses are different in magnitude and/or direction and so there exists shear stress. See full derivation ...
