5.4.9 Mises Stress

Mises stress is deined as follows:

(5.83)

where σ 1 , σ 2 , and σ 3 are the maximum principal stress, the
intermediate principal stress, and the minimum principal stress,
respectively; σ is scalar and used as index value to identify the yield
condition of materials under multiaxial stress ield. Figure 5.25
