Welding joint part 2

 

Remember :

Under Fatigue loading Conditions

• Parallel fillet = Stress concentration factor we use 2.7

              τ' = (τ/2.7)

• Transverse Fillet = Stress concentration factor we use 1.5

           (σ)'= (σ)/1.5

Special Cases

The Most important and Useful Formulas given in the table below. You have to remember at yhe time of solving Problems.

• Polar Moments of inertia ( J )

• Section Modulus ( Z )
