A Simple Energy-based Approach of Stent Elastic Properties

Simple closed-form expressions were derived for the elastic moduli of lozenge grid structure based on the convenient beam theory and energy conservation principle. Finite element analysis was employed to validate the analytical estimates of the Young’s modulus. The theoretic results were also compared with the numerical data in the literature. The results show that the calculation method of Young’s modulus obtained by energy conservation is feasible, which provides a new way for stress analysis of sandwich structures. At the same time, the cell structure proposed in this paper provides a new scheme for the design of vascular stent.
