OP - why not ask the architect what his fee schedule is?

those LH2 tanks leaked.

there is also shear transfer due to the moment. resolve the moment into a tension / compression couple at the centerlines of the two thinner sections, then transfer that load across the joint in shear.

the general rule of thumb is min of 3 full threads. and the nut material/type needs to be strong enough to fail the bolt in tension.

well what is your definition of "any"??? nothing is perfectly rigid. well, what is "some"? a sketch of this plate, with applied loads (a balanced fbd) and boundary conditions / connections would greatly help.

is there a hole in the plate with diameter equal to pipe ID? what is the application? where did the drawing come from? if it came from a customer of yours, then contact them and discuss the requirements

what is the issue? the tolerance looks to be on the left hand side, referencing datum A shown on the right.

then with displacement controlled tests, you will see load drops in the response curve which will not show up in a load controlled curve. these load drops are an artifice of the displacement controlled loading, as when there is a stiffness drop (due to damage, etc) there will be a load drop and...

was the test conduced a load-controlled or displacement-controlled?

1) suggest you delete and repost in the Aircraft Engineering forum 2) can you show a sketch of the joint? 3) is the bolt threaded into the fitting? (I hope not) or a thru bolt with proper nut/collar on it?

3 node triangles are not good. 4 noded tets are very bad. avoid both. auto meshers create triangles/tets because it is "easy". grrrrrr.

wrong. was GE engines.

I agree.

So what is the issue? Just tell the tech to remove the substituted fasteners and replace with the proper ones per the SRM.

First step in these type of problems is to get the water away from the wall, so move downspouts and regrade the outside areas.
