Simulating Non-Linear Structural Response due to Wave Impact
Hi,
I am new to this forum (and software) and I have been browsing through the forum for topics on non-linear structural response for wave-structure interaction but have not come across much of anything yet. I was wondering if DualSPHysics is capable of of simulating non-linear (inelastic) structural response in wave-structure interactions?
Cheer.

As far as I know it is not possible to currently do non-linear simulations in DualSPHysics, since the implemented DEM (and next version Chrono) models have not yet been updated to include this feature. This is still work in progress and you can read more about it in the pdf, "http://dual.sphysics.org/4thusersworkshop/data/_uploaded/PDF_Talks_4thWorkshop/Canelas_Lisbon2018.pdf". Refer to the last page as shown in this picture:

What you can do instead is do a SPH simulation with a rigid body, find out how the forces act on it and use these forces in a non-linear FEM simulation. This would be an approximation of what you want to achieve.
Kind regards
