Formulation and Solution Strategies

The previous chapters have now developed the basic field equations of elasticity theory. These results comprise a system of differential and algebraic relations among the stresses, strains, and displacements that express particular physics at all points within the body under investigation. In this chapter we now wish to complete the general formulation by first developing boundary conditions appropriate for use with the field equations. These conditions specify the physics that occur on the boundary of body, and generally provide the loading inputs that physically create the interior stress, strain, and displacement fields. Although the field equations are the same for all problems, boundary conditions are ...
