I tested and compressed the material on a testing machine, then I made a STRESS-STRAIN graph, it turns out that these are true stresses. Next, I created an Ogden model, and the Ogden model was obtained based on the true graph. Next, I made a 3D model of the tested sample and applied the same loads as in real tests, but the result is very different. Did I understand everything correctly?
