Hello All,
I've read here at HBA that you can fill a hole in aluminum pieces with an aluminum solid rivets to recover strength and prevent the hole from becoming a crack source.
First question: Is it necessary to fill that is no longer in the load path? In this scenario, I moved a bracket forward, so now there is an cantilevered aluminum angle extended beyond the load path. The stress flow would show that section to have little stress.
Second question: I have another scenario where a bracket is moved but the holes are still in the load path. the manufacturer says I should used AN bolts to "fill" the holes in the aluminum spar piece, but a solid aluminum rivet seems to make more sense. The other options are to use a stainless steel pop (standard), an aluminum pop (similar metal) as bulk, or stainless steel cherry max structural.
Just trying to understand the theory behind the path forward...
Thanks!
