A computational model for shape memory alloys

An investigation into the computational aspects of a multi-well mixture app roach to shape memory modeling is undertaken with the goals of determining its qualitative behavior as well as its efficiency in a numerical setting. A basic rate dependent model for the transformation is first introduced, fo llowed by a discussion of the steps taken to implement the constitution in discrete form. Numerical simulations demonstrate the quantitative and quali tative response of shape memory alloy structural systems to various thermal and mechanical cycles. (C) 1999 Elsevier Science Ltd.
