This paper deals with error estimates for space-time discretizations of a three-dimensional model for isothermal stress-induced transformations in shape-memory materials. After recalling existence and uniqueness results, a fully-discrete approximation is presented and an explicit space-time convergence rate of order h(alpha/2) + tau(1/2) for some alpha is an element of (0, 1] is derived.
