Radial Bending Moment

12/13/2016 6:05 AM

Hi everyone, I hope someone can help me.

I am currently calculating the maximum bending stress of a gland; for the moment, however, I am just looking at the object as a circular disc (with a hollowed out center).

I have my gland stress as being equal to:

s

Gland = ( 6 x M ) /t²

Where: t = GLAND THICKNESS M = UNIT RADIAL BENDING MOMENT (Nmm per mm of circumference). I don't really understand what it means by the unit radial bending moment. I am comparing my results with an FEA simulation but I do not know how to load my model in relation toward this "M" value. Could anyone shed some light on this please?

Consider M to be the amount of torque (force-at distance) applied (newton-meter per mm displacement of the circumference. It is analogous to a spring constant.
