Stresses in welded joint in bending
◦ Primary Shear force (vertical)
τ‘ = V/A
◦ Second momonet of area
I = bd /2
2
u
◦ Second moment area based on weld throat
I = 0.707hI = 0.707h (bd /2)
2
u
◦ The norminal throat shear stress (horizontal)
τ” = Mc/I = (Md/2)/(0.707hbd /2) =1.414M/bdh
2
◦ Total Shear Stress
