The Various Approximations of the Bimetallic Thermostatic StripSource: Journal of Applied Mechanics:;1991:;volume( 058 ):;issue: 004::page 1015DOI: 10.1115/1.2897676Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thin strip, formed by bonding two dissimilar materials, constitutes a simple thermostatic element. If edge effects are neglected, then the strip is reduced to a uniform beam, or plate, with two degrees-of-freedom. The flexure occurs only because of the bond and interfacial shear which is also accompanied by transverse normal stress. These latter stresses are very localized at the end and edges. Here, the elementary approximations, and refinements via finite elements, are presented and compared. Deflections are given with reasonable accuracy by the simple approximations, but the severe interfacial stresses are revealed only by the refinements.
