Calculating Bolted Joint Stiffness

Calculating Bolted Joint Stiffness

Calculating Bolted Joint Stiffness

we are modelling some bolted joints using CBUSH elements in FEM. can anybody help what is the difference in using huth method and using AG/L to calculate shear stiffness. Thanks in Advance.

RE: Calculating Bolted Joint Stiffness

um, huth's equation is not AG/L ... (that'd be the difference)

another day in paradise, or is paradise one day closer ?

RE: Calculating Bolted Joint Stiffness

Most of the joint flexibility is not fastener shear deformation. Have you read Huth's paper?

RE: Calculating Bolted Joint Stiffness

I have not read Huth's paper. But what I am doing wrong if i Use AG/L as CBUSH stiffness.

RE: Calculating Bolted Joint Stiffness

Agreed. Way too stiff by only considering fastener shear deformation.

Best approach - fab a two row joint specimen, test it, measure displacement. Then correlate your FEM approach to the test.
