This theory explains that the elastic failure occurs when energy per unit volume in a strained
material reaches the value of the strain energy per unit volume at the elastic limit point in the
simple tension test. Also, the maximum energy which a body can store without deforming
plastically is constant for that material irrespective of the manner of loading. What do you call
this theory
Bulk Modulus
Volumetric strain
Hook's Law
Elastic Theory
Strain energy theory
