Hi, I have included the material properties as elastic-plastic material. Probably I will try expanding a cylindrical shell inside the stent. Thank you for your advice.

Hi, I am working on stent analysis. The stress values are much higher than tensile strength. The document below has stent design with analysis. Could you please suggest me? Thanks in advance. Yomi

The solver takes almost an hour to solve each time. Could you please suggest me to get the solution in short time.

Hi Jay, The stresses are much better after applying the boundary conditions. But still they are not between yield strength and tensile strength. The design is not solved whenever I apply contacts. And if contacts are deleted it solves (stress, strain and total deformation) but the stresses are...

Here is the paperhttp://files.engineering.com/getfile.aspx?folder=afab4ca3-61ff-4f6d-b0d7-738970b6d553&file=Stent_Tubing___Understanding_the_Desired_Attributes_.pdf

Hi Jay, Thank you for the information. The following paper mentions the material properties. Are you talking about the % elongation (i.e., Elongation at UTS)in Table 1 of the paper? Please suggest me. Thanks

I have to perform expansion analysis on a crimped 180 degrees symmetry stent structure. I have to test the stent using Satinles steel316 L, Co-Cr and magnesium alloys. Boundary conditions: Fixed supports: fix the ends Pressure: 1- 2.03 I have applied displacements x- free, y=0, z= free. Still...

I have to test the stents using Magnesium alloys. I have all the information about materials. The stresses are high and the stent moves in Y direction. I am not understanding how to constraint the stent and get the expansion and crimping effect. And also I am applying pressure (0.1 - 2.03 MPa)...

Hi Jay, I am working on stent analysis. The stress values are not between tensile strength ad yield strength values. I am trying to apply a pressure of 1 - 20 atm pressure to deploy the stent and the stress values are very high. I don't understand the problem. Any suggestions?? I am using Ansys...

How to analyse stent crimping, bending, expansion in Ansys Workbench? What diameters are used in designing, crimping and expanding the stents?(If the stent nominal diameter is 3 mm) The stents are designed in Solidworks. How to apply Loads (pressure/ force),fixtures etc? Can you please help me...

I am trying to mesh and analyse 3 D stent imported from Solid works to Ansys. Whenever I try to mesh it gives mesagge that Element type 1 a solid I86, which cannot be used with the AMES command. Meshing area 301 aborted. What does this mean?

I designed a stent in Solidworks imported to ANSYS and trying to mesh the feature, it pop's out a window all the time saying define volume, volume is not defined.I am new to ANSYS and not clear what eleent types to select or how to mesh the stent.I have to apply pressure as how balloon...

Thank you, I got it.

Thank you for the reply. I read also those threads previously, I could not find mesh texture in appearances. Can you expalain me where I can find that feature in solidworks

How to draw stents in solidworks? What features are used to draw a simple stent design? I am new to solidworks.
