| Abstract |
Superelastic Ni-Ti (Nitinol) is a member of the shape memory alloy (SMA) family of
metals. The physical properties of Nitinol are highly dependant on a number of factors, including
manufacturing method, subsequent processing, operating temperature, and strain rate. These factors
complicate the prescription of material constitutive models, leading to complexities in the
computational analysis of Nitinol components. The current work explores the limitations in the
Nitinol material model available in existing commercial finite element (FE) software using a series
of specially design experimental tests and representative FE models. |
