Dear all, After carefully reading the matlab drivers of hypoplastic models, I was wondering whether the driver can simulate triaxial extension tests. As I change the constraints to reflect triaxial […]
I would like to derive material parameters based for a simulation which will implement the hypoplastic material model based on the following information: • Heavily overconsolidated • Very dense, fine […]
I am modelling an underground cavern for Compressed Air Energy Storage applications using Abaqus. To begin, I attempted to replicate the results presented in the provided paper: Damasceno, DR, Spross, […]
Hello everyone, I have just a general question how people approach the problem of spurious oscillations generated in dynamic analysis when using nonlinear soil constitutive models. I understand sometimes numerical […]
I am happy to announce that our pre-print paper, “Calibration of the von Wolffersdorff model using Genetic Algorithms”, is available on researchgate: https://www.researchgate.net/publication/342198062_Calibration_of_the_von_Wolffersdorff_model_using_Genetic_Algorithms. In this article, we propose a novel […]
Hi! I am studying the behavior of kaolin clay under cyclic loading. The strain rate is kept at such that undrained behavior is maintained. I want to use an advanced […]
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.
