Weld Joint - Butt Joint Calculation -Torque Load
The following equations will determine the shear stress applied to a welded joint under going torque loading.
Shear Stress
| Where : | |
|---|---|
| τmax | = Shear Stress [MPA,psi] |
| u | = constant |
| - for calculation in metric units u = 1000 | |
| - for calculation in imperial units u = 12 | |
| T | = torque [Nm, lb-ft] |
| W |
= section modulus of throat area of the weld [mm3, in3] |
Reference Stress Formula
| Where : | |
| σs | = Reference Stress [MPa,psi] |
| α2 | = Shear Stress [MPa,psi] |
| τmax | = coefficient of the weld joint |
