Ls dyna SPH explosion model

[abdelatif CHERAITIA]

Hello colleagues,

Has anyone here successfully implemented a fully 3D SPH explosion model in LS-DYNA?

I previously ran a stable ALE model (multi-material ALE with JWL explosive), and I’m now exploring a 3D SPH-based formulation.

Sooo i need some one to help me specially about filling this two cards

Dear Abdelatif,

 

Please see if these examples are of so0me help:

 

SPH

 

The examples in this section are from the SPH (Smooth Particle Hydrodynamics) class of LSTC. You

may access the examples separately by the menu on the left. The examples are prepared for LS-DYNA

970 and upwards.

Typically the default values serve as a starting point for SPH.

 

Have a look at this web site with previous LS-DYNA Conference papers and use a search string similar to “sph explosions”
