Question:
A material point is subjected to multiaxial stress state as shown. The deformation is elastic. The douche material has a yield stress (strength) of 500 MPa. The elasticity modulus of the material is 210 GPa and the Poisson's ratio is 0.3.
Determine,
a) the corresponding grams,
b) the principal stresses and maximum shear stress, and,
c) the safety factor according to von Mises (maximum octahedral shear stress) criterion,
