Solid mechanics, elasticity, the properties of deformable bodies.

Smoothed Particles: a new paradigm for animating highly deformable bodies.

Stress- Stress is a measure of the internal forces acting within a deformable body.

Equating the two results leads to the principle of virtual work for a deformable body:

In other words, it is the internal forces acting within a deformable body.

Specifically, it shows the intensity of the internal forces acting between the particles in the deformable body across imaginary internal surfaces.

In continuum mechanics, the loaded deformable body behaves as a continuum.

Continuum mechanics deals with deformable bodies, as opposed to rigid bodies.

A solid is a deformable body that possesses shear strength, sc.

The behavior of the cat is thus typical of the mechanics of deformable bodies.
