I am struggling with a problem that is probably simple to solve for people designing weld connections on a regular basis…
I have a bracket (HSLA SAE 050XF steel) migwelded to a tube (CRS 1015) (one side of the bracket only). This connection is under cyclic loading of let’s say 50 lb for 100,000 cycles. (To rephrase: there is a rectangular cantilever welded to a support at the top only. A force at the end of the cantilever (50 lb) creates a bending moment in the welded connection; the force is applied 100,000 times.)
I would like to be able to estimate a torque that a “good” weld should sustain. Is there a simple method allowing to simulate this torque as a product of bending moment (static) and some kind of “fatigue coefficient”?
Thank you,
Oxana
