Shear stress of 316 ss
Shear stress of 316 ss
(OP)
I'm currnetly trying to calculate a safety factor for a redesigned rotor being retained by 12 10mm bolts, I have tried to calculate the torque of the rotor (using Torque=inertia*angular Acc)and then divide by the Bolt PCD Radius, but have instead used the following eqn
Torque=Power(kW)*1000/(2*pi*N) Where n= rev/sec
Then divide by the Bolt PCD radius
Is this the better way to go (I'm pretty sure it is but just need to check. Next, The only Info I've found on Shear stress of 316SS is Von Mises theory where
Tensile stress~0.6 Shear*Stress
Is this O.K?
Cheers

RE: Shear stress of 316 ss
I've just looked up shear stress calculations in machinery's handbook and Fundamentals of machine component design and here's the following
Shear stress = 0.5 x tensile strength (Mach. Handbook)
Ultimate shear stress = 0.75 x tensile strength
Shear stress = 0.58 x tensile strength (Fund. mach. design)
Ultimate shear stress = 0.8 x tensile strength
I'm sure either formula will be o.k.
