An Efficient Generalized Plasticity Constitutive Model with Minimal Complexity and Required Parameters
Abstract Numerical analyses precision performed by software, depends mostly on the accuracy of constitutive model. Therefore, the issue of accuracy has led to significant achievements in the development of constitutive models simulating the mechanical behavior of soils. However, these constitutive models often needs to a lot of parameters to be calibrated for each type of soil, and it’s considered as a disadvantage. especially, when the model parameters should be obtained through trial and error, the number of the parameters becomes a considerable issue. This paper presents an advanced constitutive model. Despite requiring much lower number of model parameters, it provides the same level of accuracy in compression of other advanced constitutive models for sand in literature. To show that the presented model achieved to this purpose, it is evaluated by various experimental data and some predictions made by two successful advanced models in literature. Consequently, it shows the presented model can accurately predict the sand behavior under different conditions despite using smaller number of parameters. Also, the accuracy of the presented model is on a par with advanced constitutive models available in the geotechnical engineering literature.
