Curvature generation on changing the temperature of a bi-material strip
The above figure shows a schematic illustration of how curvature arises on changing the temperature of a bi-material strip. Also shown is the equation giving the resultant curvature for the case of both strips being of equal thickness (h). (The derivation of this equation, and also the corresponding equation for the case of unequal strip thicknesses, is given in the following paper: Clyne, TW, Key Engineering Materials, vols.116-117 (1996) p.307-330.)
