Module 4 Boundary value problems in linear elasticity

Module 4 Boundary value problems in linearelasticityLearning Objectives formulate the general Boundary value problem of linear elasticity in three dimensions understand the stress and displacement formulations as alternative solution approachesto reduce the dimensionality of the general elasticity problem solve uniform states of strain and stress in three dimensions specialize the general problem to planar states of strain and stress understand the stress function formulation as a means to reduce the general problemto a single differential equation.

and then replacing the strains in terms of the displacements using the stress-strain relations, Equations (4.2): C ijklu k;l;j + f i= 0 (4.10) These are the so-called Navier equations. Once the displacement eld is found, the strains follow from equation (4.2), and the stresses from equation (4.4). Concept Question 4.2.1. Navier’s equations.
