Determine the factor of safety as per tresca's max shear stress theory
If a machine part is made of Ti-6A1-4V titanium and a critical point in the material is subjected to plane stress,
such that the principal stresses are σ1 and σ2 = 0.501, determine the magnitude of σ1 in MPa that will cause
yielding according to (a) the maximum shear stress theory, and (b) the maximum distortion energy theory.
Hint: Refer to the inside cover the textbook for material section properties.
1. We can visualize the factor of safety for an arbitrary stress using a surface in principal stress space. For
a ductile material that yields according to a von Mises criterion with a yield stress σy, sketch the von
Mises surface in σ₁ - 02 space and sketch the stress surface that corresponds to a factor of safety FoS =
2. For a brittle material that yields according to a max normal (Rankine) criterion with a tensile strength
Gyt and a compressive strength σvc = 20yt, sketch the yield surface and the surface that corresponds
to a factor of safety FoS = 2.

Two points A and B on the surface of the frame were found to be most critical.
