Weld Joint - Butt Joint Calculation - Bending Load Perpendicular to Weld
The following equations will determine the normal stress applied to a butt welded joint under going bending loading perpendicular to weld joint.
Normal Stress
| Where : | |
|---|---|
 |
= Normal stress [MPa,psi] |
| u | = Constant |
| - for calculation in metric units u = 1000 | |
| - for calculation in imperial units u = 12 | |
 |
= Bending moment [Nm, lb-ft] |
| W |
= Section modulus of throat area of weld [mm3, in3] |
Reference Stress
| Where: | |
 |
= Reference stress [MPa,psi] |
 |
= Normal stress [MPa,psi] |
 |
= Coefficient of weld joint |
