Modeling and experimental analysis of the hyperelastic thin film nitinol
Source abstract
Abstract
Many flexible electronic devices or endovascular biomedical devices require large deformation; however, potential materials produce limited elastic response, that is, 10% when 400% is required. In this article, a finite element model is used to design a hyperelastic thin film nitinol structure containing geometric fenestrations. The hyperelastic response is dependent upon geometric factors that produce buckling. Parametric studies provide the influence-specific parameters have on buckling load. These results are used to select three designs to manufacture and test. Experimental results indicate that elongations greater than 700% are possible.
