Dear Community, I want to include a non-local regularization technique in the built-in Mohr-Coulomb model of abaqus to capture the strain-localization effects. I am trying to find the original VUMAT […]
Good evening, everyone. I find it difficult to apply equations (13) and (14) of Herle’s publication “Determination of parameters of a hypoplastic constitutive model from properties of grain assemblies”. As […]
Dear Prof. David Mašín Greetings I would like to discuss with you an issue. I have a problem in my simulation on ABAQUS. The problem in the simulation results is […]
Hi everyone: I am trying to use SANISAND as the constitutive model of soil, and use ABAQUS software to simulate pile-soil interaction. First step is “Geostatic”, the second step is […]
Dr. Masin I have downloaded the most recent dll for Plaxis that includes the HypoPlastic model for Clays that you developed. I see two new parameters (Gvh0 and n), both […]
Dear all, I am trying to model soil-monopile interaction (3D) in ABAQUS/Standard in order to perform subsequently a cyclic and dynamic analysis. For the soil I am using the SANISAND […]
Hi everyone: I am trying to use SANISAND as the constitutive model of soil, and use ABAQUS software to simulate pile-soil interaction. Is it better to choose “Static, Genaral” analysis […]
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.
