u2.01.05 Stresses, efforts, forces, and deformations

Summary:

This document defines the quantities characterizing the stresses, forces, and deformations within a structure in a finite element calculation in motion and how this is translated. The expression of these quantities is given for mechanical finite elements: 2D or 3D continuous medium, shells and beams.
