Stress & Strain
GATE 2021
Medium
The von Mises stress at a point in a body subjected to forces is proportional to the square root of the
- Atotal strain energy per unit volume
- Bplastic strain energy per unit volume
- Cdilatational strain energy per unit volume
- distortional strain energy per unit volume
Explanation
The von Mises (maximum distortion-energy) theory states that von Mises stress is proportional to the square root of the distortional (shear/deviatoric) strain energy per unit volume, excluding the dilatational (volumetric) component.
