Shear stress of 316 ss

thread404-8479

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

Craig

RE: Shear stress of 316 ss

The only valuable information I ever found on shear stress is

Sy(shear) = 0.577 * Sy(tension)

Ref: Mechanical Engineering Design, 4th ed., p. 234
Shigley & Mitchel
McGraw Hill

RE: Shear stress of 316 ss

Berry,

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.


Regards


Bryan

Here is a web site that has mechanical properties of a lot of different materials:

Hope this helps,
