Auricchio F., Stefanelli U. Numerical analysis of a 3-D super-elastic constitutive model. Preprint ercim.cnr.ian//2002-1306, 2002.
This note deals with the efficient approximation of a nonlinear constitutive relation arising in the study of the mechanical behavior of shape memory alloys at constant temperature. In particular, a variable time-step discretization is investigated, sharp error estimates of optimal order are provided, and some numerical results relative to proportional and non-proportional loading tests are included.
