| Abstract: | In view of the problems of the current research on the braid stent,the geometry model and finite element model establishment,material model selection and boundary condition setting are completed.The method to calculate the radial force of the esophagus stent is presented.The radial force of the stent with different wire numbers,different wire diameters and different leads are computed.The analysis results show that the more the wire number of the stent,the longer the radial force;the larger the wire diamete... |
