Hi, I'm looking for a possibility to evaluate tensile test results. That means I have done a tensile test analysis in hyperworks (imposed velocity...) and the same test also on a test bench in reality. So I have the real results (force/displacement diagram, stress/strain diagram) and want to compare the simulation with these results. But I couldn't find a way to do this comparison. Do you have any idea how to handle the simulation results? Maybe create a stress strain or force displacement result in hyper view/hypergraph? Thank you very much for your help!
Hi, 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. Greetings, Friendly
