Ductile Coulomb Mohr Criterion: Different Yielding Strengths in Compression vs. Tension

LECTURE 13:
Here materials with different yielding strengths in compression than in tension are introduced, and the Ductile Coulomb Mohr failure theory is derived from the maximum shearing stress concept and the geometry of the Mohr's circles associated with tensile and compressive yielding data. Ductile iron is spotlighted as one example of a material that can exhibit asymmetric tensile and compressive yielding strengths. An example is completed in which DCM theory is used to evaluate a factor of safety for the critical location on a ductile iron shaft subjected to bending and torsion due to a belt drive. The load line for this state of stress is plotted along with the DCM failure locus. The algebraic evaluation of the safety factor is verified against the geometry of the load line/failure locus plot.

22:30 Why not Syt/2 - Syc/2 based on the fact that the cordinate location for Syc is negative.
Great content btw. It helps me at my workplace alot!

Excellent video again thank you. But in example, why didnt we take shear stress into account at the critical point? doesnt it occur?
