ABSTRACT

In the present chapter, the virtual work theorem is reviewed and the ‰nite element method for multiphase geomaterials is presented.

6.1 VIRTUAL WORK THEOREM

Finding the displacement and the stress ‰elds that satisfy the constitutive equations, such as the elastoplastic model, the strain-displacement relations, the equations of motion, and the initial and the boundary conditions, is called an elastic-plastic boundary value problem.
