Web1 nov. 2024 · MAT_SOIL_AND_FOAM_FAILURE is a constitutive model used to simulate soil, and in this model, a curve about the relationship between pressure and volumetric strain can be imported. Due to the existence of this curve, it is possible to explore the performance of water jet eroding hydrate materials under different confining pressure … WebLS-DYNA simulations, the soil was modeled using the material model MAT_005 Soil and Crushable Foam. Two approaches were used to represent the soil: a hybrid approach that combined Lagrange and Smoothed Particle Hydrodynamic (SPH) methods and the Multi Material Arbitrary Lagrangian - Eulerian (MM-ALE) method.
