      Hello. I often have questions about Ansys Autodyn, and I would appreciate your answers. In Ansys Autodyn's Material Data Input, when I select Steinberg Guinan for Strength, there is an item called Yield Stress. I want to increase the value of Yield Stress, but do I need to change other values as well? I'm really struggling, so I would be happy if someone could answer this.

      The entire data set of Steinburg Guinan model was created from experiments. Usually it is not the best practice to just change the value of initial Yield Stress without changing other data accordingly.

      Thank you for your answer. If the initial yield stress is changed, what other values need to be changed？
