hysteretic material

[Joker]

could you please tell me about hysteretic material parameter or give me some reference about this material? I want to know the hysteretic rule exactly and the equation. The information in wiki command manual is too limit to master its behavior. I need help~!!!

Unfortunately, there is no reference for hysteretic material. Professor Filippou, who is the developer of the material, never wrote a paper about it. The OpenSees source code is the only place where you can find the equations you are looking for.

See this page for the effects of changing the pinching parameters

If you need the exact equations, see the source code
