The quasi-static evolution of a body made of an inelastic, rate-independent material is determined by a minimum principle, according to which the evolution takes place along the direction which minimizes the increment of the sum of two functionals, free energy rate and dissipation rate. Specific examples from plasticity, fracture, and adhesive contact with damage are given.

Abstract
The quasi-static evolution of a body made of an inelastic, rate-independent material is determined by a minimum principle, according to which the evolution takes place along the direction which minimizes the increment of the sum of two functionals, free energy rate and dissipation rate. Specific examples from plasticity, fracture, and adhesive contact with damage are given.File in questo prodotto:
