Explicit solutions example

[diego.rusnighi]

Hi,

I'm looking for information about explicit solutions in Nastran.
I found a couple of examples in the tutorial but I would like to understand the potential better. Are there other sources/examples?
In 2024 in the examples section in my installation profile I found an assembly Buckle_explicit Dynamics.iam, is it part of some tutorial?

Thanks in advance

Hello @diego.rusnighi what type of challenge do you want to takle? In general this type of simulation is ideal for events that take place in less than a second. 

Best Regards.

Hi @lucmartzz,  

I'm doing the first tests with explicit solutions to try to save time compared to classic analyses. But in reality I'm trying to understand how effective and guaranteed they are.
The idea is to try functions such as bending, tube forming, snapfit, roll bending,

Non-linear buckling, rapid compressions of gaskets...
Examples would be useful

@diego.rusnighi please take in count that Explicit Dynamics is ideal for mechanical events that takes less than 1 second.
