Curvature effect on nitinol aortic stent

high i am a student doing a project on curvature effect on thoracic stent. I want to curve the nitinol stent in abaqus. I am using RSURFU and doing static analysis. But am not able to curve it. Also when using implicit dynamic analysis with quasi static apllication my KE is high and comparable to IE. So can any body help me. Crimping and expansion is not a problem.

Hello

 

perhaps the Abaqus extension 'Adjustable Rigid Torus' might be helpful. Check

They mention an example involving bending

 

Good luck
