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 |
