WebQuestion: • Define notch strengthening and its relevance in engineering materials. • Explain in general what are triaxial state of stress and their influence in plastic deformation of materials. • Give a brief discussion of stress concentration factor. WebPrincipal plane:- It is the oblique plane that experiences zero shear stress. For the components subjected to biaxial stresses, there are two planes on which the value of shear stress is zero. Thus to find a position of this principal plane (θ𝗽) from the reference plane, put τ τ = 0 in the equation of τ τ. 0 = ( σx − σy 2)sin2θP ...
