Hi Meng, it is here: https://soilmodels.com/download/plaxis-umat-sanisand/ in file implementation/umat.for. David
thank you very much!,but my meaning is that where can I find related literature about explainning the formula of the above code.
I think this is simple switch allowing to define friction angle directly in degrees, or as M=q/p at failure. If below 5, the algorithm assumes that you entered M, if above 5 , the algorithm assumes you entered friction angle in degrees. This is just a technicality about how to input parameters, I do not think there is in any literature for it. David
