What is 3D Stress and Strain Analysis Guide about?

The document describes the formulation of the finite element method for 3D stress analysis. It presents: 1) The 3D state of stress and strain is related through the constitutive relationship and depends on the nodal displacements (u,v,w). 2) The strain-displacement matrix [B] relates the strain at each node to the nodal displacements and is assembled using shape functions and their derivatives. 3) The stiffness matrix [K] for each element is obtained by integrating the product of [B] and the constitutive m
