bimetal design guide
(OP)
I am working on a product that has a bimetallic strip that is used for temperature compensation. It is a U-shaped strip, with the "legs" of unequal length. I am attempting to calculate deflection, etc., but don't know where to start - it is more complicated than the cantilever beam theory stuff I learned in school. Does anyone know of any sources or design guides regarding bimetal material or deflection of irregular shapes?





RE: bimetal design guide
A good place to start would be to look at Roark's Formulas for stress and strain by Warren C. Young. This may help you get started. I am no expert on this, but that is where I would look.
RE: bimetal design guide
This paper gives an expression for the radius of curvature for an unrestrained bimetallic strip which could give you a start.
Cheers the noo!

This company used to be part of Texas Instruments and they have an excellent bimetal design guide that has material properties and equations for several bimetal shapes (including U-shape) I believe. I used to have the manual when it was a TI publication and it was extremely helpful.
Good luck,
