Web2.4.4 Elastic Strain Energy. The elastic strain energy consists of two main components: one resulted from stress field associated with dislocations, E dis, and the other one due to the applied stress, E σ. In the following the elastic strain energies for a homogeneous and an inhomogeneous dislocation distribution will be deduced, respectively. WebAn object or material is elastic if it comes back to its original shape and size when the stress vanishes. In elastic deformations with stress values lower than the proportionality limit, stress is proportional to strain. When stress goes beyond the proportionality limit, the deformation is still elastic but nonlinear up to the elasticity limit.
