TM will definitely change for different materials.
You can calculate the Tangent Modulus of the material using:
TM = ('Ultimate Tensile Strength'-'Yield Strength')/('Elongation at UTS'-'Elongation at YS').
Elongation at YS = (Yield Stress)/(Young's Modulus).
For Elongation at UTS; you'll...
Thank you cvan and flash; I will work with these methods and get back to you over time.
Yomi; are you sure you are defining a non-linear material model for the case? This was what I was doing wrongly for some time initially; I used a bi-linear stress-strain curve eventually; (Bi-linear...
thanks for that cvan!
i do believe that while your crimping/expansion analysis does infact represent the actual process quite realistically (crimpers do actually used multiple surfaces/plates!), the analysis i've performed suffices for the relatively simple model that i am looking at.
i would...
I was defining the wrong material models all this while! Haha thanks for that man.
Okay, even more problems (I'm an FEA newbie, forgive me!)
HAve a look at this pdf I am attaching. THanks!http://files.engineering.com/getfile.aspx?folder=2ed4f2c8-4e39-437c-b5f8-82affbeff65a&file=STENTPROBLEMS.pdf
Hi,
I'm trying to crimp a stent (tubular medical device) on Workbench 14.0, external diameter of the stent being 2mm and thickness being 0.081mm.
I have assembled the stent and a thin-surface (diameter 3mm) around it on SolidWorks. Using 'Transient Structural', I have applied a 'Cylindrical...
