摘要: In this article we consider the numerical approximation to time-dependent viscoelasticity equations with an Oldroyd B constitutive equation. The is stabilized by using a streamline upwind Petrov--Galerkin (SUPG) for We analyze both semidiscrete and fully discrete approximations. For discretizations prove existence of, derive priori error estimates for,
