Question

​​​​The yield stress of a metal in uniaxial tension is $200 \text{ MPa}$. According to von Mises yield criterion, the yield stress (in $\text{MPa}$) of the metal in pure shear is closest to

• A. $115.5$
• B. $100.0$
• C. $66.7$
• D. $141.4$

Answer 1

A=115.5

yield in shear happens at about 0.577 times the tensile yield stress.

Multiply the given yield tension with 0.577
