Distortion Energy Theory is suitable for Ductile materials. When the strain energy of distortion per unit volume absorbed at a point is equal to the strain energy of distortion per unit volume at any point in a bar stressed to the elastic limit under the state of uniaxial stress as occurs in a straightforward tension/compression test, it is said that inelastic action at any point in the body, under any combination of stress begging, is occurring.

Suitable Theory for Ductile Materials
Distortion Energy Theory is suitable for ductile materials. According to the distortion energy theory, failure results from part distortion rather than volumetric changes in the component (volumetric changes do not result from distortion, which produces shearing). However, there is a condition, that when a material is under hydrostatic pressure, this Distortion Energy theory can not be applied.
The observation that ductile materials under hydrostatic stress (equal principal stresses) exhibited yield strengths significantly higher than those determined by the simple tension test led to the development of the Distortion-Energy (DE) theory.
Summary:
The Theory Suitable for Ductile Materials is
For ductile materials, the Distortion energy theory is the best suitable theory. The ductility of a material is its ability to be drawn into thin wires or threads. A material that can be converted into thin wire because of its physical property is called ductile material. The ductility of a material depends upon the elements present in it.
