KIRCHHOFF, GUSTAVE ROBERT.

Über das Gleichgewicht und die Bewegung einer elastischen Scheibe.

Berlin, G. Reimer, 1850. 4to. Without wrappers. From "Journal für die reine und angewandte Mathematik. Hrsg. von A.L. Crelle", 40. Bd., Heft 1, pp.IV,92,(2) pp. and 2 lithographed plates. Entire issue offered with titlepage. Kirchhoff's paper: pp. 51-88.

First printing of Kirchhoff's milestone paper on "the theory of plates in which we find the first satisfactory theory of bending of plates...he established the correct mathematical expressions for the potential energy,...further he shows that are only two boundary conditions and not three, as was supposed by Poisson...The advent of this theory of plates was a very great step foreward in the theory of elasticity, and it has become especially importent lately owing to its wide application in the design of various kinds of thin-walled structures." (Timoshenko p. 253-54).
