How to create part blast resistance

im trying to create destructible vehicles and cant figure out how to get the explosions to not just break the entire vehicle from one hit

im trying to give parts blast resistance and i dont know how
im trying to get something like

in these games when you blow something up, the explosion wont always destroy the welds holding the parts together
this is what i want

You could probably use a event called hit at Explosion effect and make each part its own blast resistance attribute and do smaller and smaller after each hit like some sort of hp.
