Yield Strength for RTV

Yield Strength for RTV

Yield Strength for RTV

(OP)
Hi there... Just wondering if anyone can help me with a little problem I'm having.

I'm doing some material studies on a Silicone based RTV and I have a Young's Modulus value of 107 GPa. Now here's my question... Can I use the offset method to find the yield strength of this material? That is, can I offset the stress curve by 0.2% to find the yeild strength for this material? If so, how would I actually go about doing that? Just multipy the young's modulus value by 0.2? Something like this?

107x0.2=x; x+107=y

Any help is appreciated.

Arg. Nevermind... I don't think that will work because Young's modulus is just the slope of the stress curve. If I wanted to use the offset method I would need to know the value of some point along that curve, and I don't.

Oh well... Maybe I can find it somewhere else.

RE: Yield Strength for RTV

No. Young's modulus is a measure of the slope of the initial linear portion of stress-strain curve. It is a measure of the stiffness of the material.
The yield strength by the offset method is found at the intersection of an actual stress-strain curve with a  straight line parallel to the above slope, offset by 0.2% on the strain axis.
