Strain

Hookc's law is the basie law in clasticity. In mechanics and physics, Hooke's law of elasticity is an approximation ihat States that the cxtenslon of a spring is in direct proportion with the load applied to it. In simple this law says that strain is directly proportional to stress. The generalized Hooke’s law can be used to predict the deformations caused in a given materiał by an arbitrary combination of stresses.

The linear relationship between stress and strain applies for ® ^
