MultiaxialCyclicPlasticity

Post by syb »

Hi everyone,

I'm trying to use the MultiaxialCyclicPlasticity constitutive model for an initial analysis, but it’s not included in the OpenSees documentation for constitutive models. I found the source code for this model on GitHub. By default, the material stage is set to 2 (plastic stage), but I need an elastic stage for the initial analysis.

It seems that the updateParameter function could change the stage, but it looks like a parameter needs to be defined first before calling updateParameter. I tried using parameter 1 element 1 material 1 MaterialStageID to define it, but this didn’t work.

Could anyone advise on how to set up this constitutive model for an initial analysis?

Thanks!
