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.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
