I implemented a unified dynamic soil model, but PLAXIS doesn’t calculate any strains, and it prints zero (or some times NaN amounts) into a text file. I’d like to know […]
Hi all, I wanted to ask if anyone has experienced this error before when running the Hypoplastic UMAT (umat_hcea.for) on Abaqus? “Abaqus Error: The executable standard.exe aborted with system error […]
Hello.. I am using SaniSand constitutive model, for the simulation of the behavior of onshore wind turbine using plaxis 3d. The dll file published in the website request the determination […]
Dear all I have some laboratory test of Pescara sand and I’m trying to find the von Wolffersdorff parameters of this sand. So I have used ExCalibre with the data […]
Hi, I just came across some problems with the implementation of the “Sand Hypoplasticity Model” in Plaxis. I wanted to to perform a simulation of an oedometer test on a […]
Dear all Is the basic Hypo-Plastic model (Wollffersdorff’s model) suitable for 3D models? Can I analyze 3D models with this UMAT? (https://soilmodels.com/download/umat-hyposand-uibk/) Thank you Sobhan
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
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.
