Hi all ... Is there a way to find/calibrate material parameters for johnson and cook material model using experimental data in Abaqus? .. As far as i know abaqus has something called as data editor with which Hyperelastic materials models can be calibrated with experimental results. If not is there any other way arround to do calibration of material parameter with abaqus.
Material Parameter Calibration
As far as I know Abaqus does not have a way to calibrate material models other than Hyperelastic.
The material calibration problem is really an optimization problem. We've used our software, HEEDS, on this type of problem many times with excellent results. Email me or hit our contact page on the website at the link in my signature if you're interested.

RE: Material Parameter Calibration
As Marcus just mentioned, it is really an optimization problem and Abaqus has limited features for it. Our company, Veryst Engineering, has a software tool MCalibration that calibrates ALL material models available in Abaqus. See the link below for some examples and screen captures.
