Finite Element Methods with Recovery for Problems of Elasticity and Viscoelasticity

Abstract . The paper is concerned with the numerical solution of problems of linear elasticity and viscoelasticity. First , in the context of finite element solution of problems of linear elasticity, we discuss various aspects of finite element gradient recovery, su­ perconvergence, a posteriori error estimation and adaptivity. These form the basis for the spatial approximations in our numerical techniques for problems of viscoelasticity.
