I have a question concerning the Input of true stress vs effective strain curves in ls-dyna:
I would like to insert several curves for different strain rates for MAT_24 using the table Option, because I dont know the Cowper-Symonds constants.
These curves are from experiments and range from the yield point up to the ultimate tensile stress.
The remainder is missing and that is why I have used the voce equation for it. Does it make sense to insert several Points using "Load xy Data" or just up to 8 Points?
I plan on crushing a thin walled tube of AA6060.
