DESIGN 1 (uniform diamonds)
The simplest stent design is given by the cylindrical frame with all struts of equal length. Here we consider a stainless steel stent (316L) with 8 vertices in the circumferential direction and 7 vertices in the longitudinal (axial) direction is considered. The length of each strut is 6mm. The stent has been expanded to the radius of 1cm into its reference configuration.
The stent is subject to a uniform pressure load of 0.5 atmosphere applied to the exterior wall. As a result, the stent deforms and exhibits both the axial and longitudinal displacement.
