Mixtures/Suspensions of different materials for Abaqus SPH modeling

Aaborta · Feb 3, 2021

Hello Everyone,
I was wondering if anyone could provide some information on how to make material mixtures (clay + water + coarse particles) for SPH modeling using Abaqus. For example, gravels of different sizes (uniform or non-uniform sizes) mixed within a clay dispersion. At the same time identify their volume fractions (e.g. clay fraction and gravel fraction). Thank you so much for stopping by this post

I'm not familiar with the features in Abaqus but you may want to look into Discrete Element Method (DEM) for this type of problem. It's a lagrangian method which is conceptually similar to SPH but designed for things like sand and gravel. For example my company carries a product called Granuleworks which can be coupled with another solver called Particleworks for handling the water in your problem. This page has some additional information that might be helpful:
