Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

I am not very sure with this kind of weld check, could you give me some help and suggestion?

Details as following:

Given:

Ft=force in y direction

Lt=distance between Ft action point and weld group geometric center(y direction)

Fl=force in x direction

Ll=distance between Fl action point and weld group geometric center(x direction)

L1=weld 1 length

L2=weld 2 length

L3=weld 3 length

t=weld throat

Ix-=moment interia about x axial

Iy-=moment interia about y axial

r=the max distance form center

Soluation

find out the max weld stress

My solution is this,

First move Ft and Fl to the geometric center get the tension and shear stress

Then take tousionT=Ft*Lt+Fl*Ll(or Ft*Lt-Fl*Ll) take the

stress σ=T/(Ix+Iy)*r,and distribute the result to x and y direction,

and finally get eqivualent stress

Am I right?

Thank you for your help and suggestion.
