Physical Interpretation of The Von Mises Yield Criterion
Hencky (1924) offered a physical interpretation of von Mises criterion suggesting that yielding begins when the elastic energy of distortion reaches a critical value. For this, the von Mises criterion is also known as the maximum distortion strain energy criterion. This comes from the relation between and the elastic strain energy of distortion :
- with the elastic shear modulus .
In 1937 Arpad L. Nadai suggested that yielding begins when the octahedral shear stress reaches a critical value, i.e. the octahedral shear stress of the material at yield in simple tension. In this case, the von Mises yield criterion is also known as the maximum octahedral shear stress criterion in view of the direct proportionality that exist between and the octahedral shear stress, which by definition is
thus we have

“Oh, don’t be so fussy. Your body, after all, what is it? Just a physical covering, that’s all. Worth, chemically, 32 cents.”
—Sidney Buchman (1902–1975)
“We cannot shape our children according to our ideas,
We must keep and love them as God gave them to us.”

“While the white man keeps the impetus of his own proud, onward march, the dark races will yield and serve, perforce. But let the white man once have a misgiving about his own leadership, and the dark races will at once attack him, to pull him down into the old gulfs.”
—D.H. (David Herbert)
“Faith in reason as a prime motor is no longer the criterion of the sound mind, any more than faith in the Bible is the criterion of righteous intention.”
