Analysis of the Flexural Rigidity of Vascular Grafts by Numerical Simulation Methods

Resumo

Abstract—A numerical evaluation was performed to assess the efficiency of reinforcement of small-diameter vascular grafts made of polymeric materials. Based on the finite-element analysis, an algorithm was developed to find the optimal parameters for the reinforcing layer and to evaluate its stress–strain state under conditions of longitudinal bending simulation. The findings may be useful for industrial and laboratory trials in studies of the strengthening properties of similar products.
