When exerting a force on an isotropic material , the deformation of its dimensions is proportional to the exerted force .
There are Two Types of deformations:
1. Elastic: the material gains back its original shape
2. Plastic: the deformation is permanent.
Hooke's Law: A Law stating that, in a linear system, the restoring force is proportional to the displacement of the body, acting in a direction as to restore equilibrium.
F = restoring force [N]
k = spring constant [Nm-1]
x = elongation of material [m]
The exerted force on a body is directly proportional with the change in its length.
Generalized hook’s law:
