Well, hei!
A design engineer have asked me to check a flange (please see pic 1). He wants to know what is going to break first eventually: the flange or the bolts.
Lets say under a bending moment, statically.
So... I was wondering how to estimate the stiffness of the connected parts: 1, 2, 3, flange. The memebers 2,3,flange are connected in parallel: 1/k=1/k2 + 1/k3 + 1/kflange is valid. But what about the member 1?
I am so confused and curious at the same time.
Would it be right to use Ansys to estimate the stiffness of the multilayer member?
What I do is to apply a compression force simulating the bolt pretension (please see pic 2). Get deflection and then calculate the stiffness.
I get reasonable magnitudes and all seems fine.
But would like to hear if my reasoning is right.
Thanks.
