Question
The uniaxial yield stress of a material is 300 MPa. According to von Mises criterion, the shear yield stress (in MPa) of the material is __________
Correct answer
171 to 175
Solution
According to the von Mises criterion, also known as the maximum distortion energy theory, the relationship between the yield stress in uniaxial tension () and the yield stress in pure shear () is given by:Given the uniaxial yield stress, MPa.We can calculate the shear yield stress, , as follows:Since ,This value falls within the given correct answer range of 171 to 175.
