Expanded mixed finite element methods for the problem of purely longitudinal motion of a homogeneous bar

In this paper, expanded mixed finite element methods for the initial-boundary-value problem of purely longitudinal motion equation of a homogeneous bar are proposed and analyzed. Optimal error estimates for the approximations of displacement in L^2 norm and stress in H^1 norm are obtained.
