Is it possible to simulate the impact of particles on a deformable structure and capture the resulting structural deformation simultaneously in Ansys Rocky?

Hi

I do not think it can (especially NL, say large strains and NL material/plasticity or hyperel., etc.), not sure, perhaps it can only be done by coupling -> below
You can though transfer Rocky forces to Mechanical static. Chapter 15: Tutorial – Transient Structural

 

To do it all in one single tool:

LS-DYna can (DEM + Lagrange solid).

You'll get the impact force from Rocky, so I assume you can bend something in Mechanical. Are you looking at many smaller impacts (sand blasting or the like) or few large impacts as that will also determine the best approach.

I wanted to simulate many smaller impacts on a structure. Also I would like to know whether it is possible to perform one-way and two-way coupling between ANSYS Rocky and Explicit Dynamics/LS-DYNA. I would like to use either Explicit Dynamics or LS-DYNA  because the required engineering material database for my model is not available in the Transient Structural platform.

A: See this similar post here:

Rocky (DEM) – LS-DYNA coupling: official support status

This is what is sup.:

2.3. Ansys Rocky Coupling with other Ansys Software

(1 way and 2 way Transient Structural).


As we said use DEM inside LS-Dyna and use any MAT inside LS-Dyna you want :):
