Hi All,

I hope u all will be aware about the limitations of WRC 107/297 with regard to the geometric parameters(radius/thk ratio etc..) and the curve values.

I understand from the foresaid bulletins that the theory on which they are based are not valid if certain limitations are exceeded and so obviously the stresses calculated would not be reliable. How Coade deal with this?.

I've also seen some client specifications calling for FEA when such limitations are exceeded. I even know certain companies who write these spec's do not follow this requirement due to commercial implications.

Can somebody put some light on this issue?
