  Hello,
  in the ls dyna software for mat197, in the previous relationships, up to behavior V was considered, but in the new versions, behavior VI and VII have been added. I need the type of formula used in this type of material. Can you send me the used formulas?

  You've contacted the MAT_197 developer and were told, in the context of this specific request, " “The algorithms and formulae in LS-DYNA are the intellectual property of Ansys inc. Apart from the contents of published papers, other information cannot be shared.”

  Question is unclear. But regardless, in consideration of my previous reply, please have your Ansys distributor contact the developer should you wish to pursue this. Do not contact the developer directly.
