Circumference Butt Weld Stress with Combined Shear and Axial Loading Calculation

Weld Design Menu

The following equations will determine the resultant reduces stress and comparative stress of a welded joint under going axial loadings.

Resultant Reduced Stress Formula

Resultant Reduced Stress Formula

Where:

= Resultant seduced stress [MPa,psi]

= Normal Stress [MPa,psi]
= Shear Stress [MPa,psi]

Comparative Stress  Formula

Comparative Stress Formula
Where:

= Comparative stress [MPa,psi]
= Normal stress  [MPa,psi]
= Shear stress  [MPa,psi]
= Conversion coefficient of weld joint
