Mat 011 Steinberg Guinan translation to LS-DYNA keycard

  Hello all,
  I posted previously about the Steinberg-Guinan model and implementing it in Workbench LS-DYNA as a keycard input. I have since attempted this but the formatting for the actual equation parameters is confusing, particularly the derivative terms. They are not well labeled in the LS-DYNA theory manual. Does anyone have an example material for Mat 011 in keycard format that I can compare to? Thank you!

  Please see below sample input (for illustrative purposes only). The model units are mm-kg-ms.

  Hello,
  Thank you for the reply. The issue I am having is translating the existing Workbench models into the LS-DYNA keycard format so I can run it in a keyword snippet. Most of the terms are clear when comparing the Workbench labels to the LS-DYNA manual, but I am not clear on these three terms in particular. I am not sure if they are BP, H, F, or other terms. The manual recommends the original paper by Steinberg and Guinan as a reference, but I cannot locate a copy... Is my question more clear this way? Thanks again for your answer.
