Blast Simulation: FSI vs Load as Pressure

AI Thread Summary
For blast simulations on vehicles, the choice between Fluid-Structure Interaction (FSI) and using load as pressure is debated. National codes, such as those in the UK, specify applied loads for impulsive forces on structures, which may influence the decision. Research from the Transport Research Laboratory (TRL) supports the traditional uncoupled approach. While LS-DYNA offers FSI capabilities for blast simulations, this feature is relatively new and may not be as widely adopted yet. Ultimately, the decision should consider existing standards and the specific requirements of the simulation.

Hi all,

Planning to do an Blast simulation on a vehicle.
Should I go for FSI or Use the load as pressure.
Please throw some light on the same.

Thank you,
TheSymbol

Have a look at vehicle impact standards in your national code to see how they treat impulsive forces on barriers, bridges and other structures due to impact.
The UK codes state a specific applied load. There is much TRL research about this published.
 
This sort of thing is mostly still done uncoupled.
LS-DYNA does have FSI capability for blast, specifically, but it is rather new.
