I am getting the same type of problem when I crimped the stent using a frictionless contact between the crimper and the stent strut. I want to crimp it radially and find out the minimum metal to metal diameter, but I got the same problem. Strut passed with another strut and not getting satisfactory crimping in static structural.nyou are using the 12 plates I think (for the full model), can you please tell me which material you have been used for the crimper (plates), and have u defined the contact between plates? and you are doing in static structural or explicit dynamics.n
