I recently discovered this useful tool.
For the preliminary case, I was trying to implement a simple linear elastic uniaxial extension optimization problem using ABAQUS/Explicit. The aim is to estimate the optimum material properties.
I have written the code and I need to compare the displacement field with that of experimental data.
The code, however, is converging after only three iterations and showing the initial estimate of material properties to be the optimum values.
However, based on the experimental data, the optimum values should be E = 300 GPa and Poisson's ratio = 0.3.
I'm attaching the complete code for reference. I would be grateful if someone could look into the matter.
