| Popis: | An error analysis is provided for the spatial approximation by the finite element method of a nonlinear time-dependent problem which models the antiplane shear deformations of a thermoplastic material. This problem consists of a system of two coupled partial differential equations with velocity and temperature unknowns. Optimal order error estimates in the L 2 norm are given for each of these. |
