Analytical and Numerical Solution and a Multi-Objective Optimization for Auxetic Stents with Various Geometries, M.Sc. Thesis Sharif University of Technology ; Nourani, Amir (Supervisor)
Abstract
The present study examines the mechanical properties of auxetic stents with various types of structures. Geometries was parametrically modeled and the design of experiments (DOE) was developed by defining the elastic properties of the stents and using the response surface method (RSM). Finite element (FE) analysis was performed in order to find a polynomial relationship between the geometric parameters as inputs and the elastic parameters as the outputs. Then, the optimal stent was obtained in terms of elasticity parameters by using RSM and NSGA-II methods and the two-dimensional Pareto front was plotted. For instance, the optimal parameters of the Re-entrant stent including flexural...
