Hardcover. Condizione: Good. xxi, [3], 544, [4] pages. Tables. Figures. Formulae. Name of previous owner [H. D. Hoeskstra] and a date in 1929 inside front cover. Pencil notation on fep and page. 249. Cover has some wear and soiling. In two parts, the first is analytical/theoretical and the second is experimental. When an elastic material is deformed due to an external force, it experiences internal resistance to the deformation and restores it to its original state if the external force is no longer applied. The elasticity of materials is described by a stress-strain curve, which shows the relation between stress (the average restorative internal force per unit area) and strain (the relative deformation). Because the elasticity of a material is described in terms of a stress-strain relation, it is essential that the terms stress and strain be defined without ambiguity. Typically, two types of relation are considered. The first type deals with materials that are elastic only for small strains. The second deals with materials that are not limited to small strains. Clearly, the second type of relation is more general in the sense that it must include the first type as a special case. Stepan Prokopovych Tymoshenko (December 23, 1878 - May 29, 1972), was a Ukrainian and, later, an American engineer. He is considered to be the father of modern engineering mechanics. A founding member of the Ukrainian Academy of Sciences, Timoshenko wrote seminal works in the areas of engineering mechanics, elasticity and strength of materials, many of which are still widely used today. Having started his scientific career in the Russian Empire, Timoshenko emigrated to Yugoslavia during the Russian Civil War and then to the United States. In the fall of 1906 he was appointed to the Chair of Strengths of Materials at the Kyiv Polytechnic Institute. The return to his native Ukraine turned out to be an important part of his career and also influenced his future personal life. From 1907 to 1911 as a professor at the Polytechnic Institute he did research in the earlier variant of the Finite Element Method of elastic calculations, the so-called Rayleigh method. During those years he also pioneered work on buckling, and published the first version of his famous Strength of materials textbook. In 1911 he was awarded the D. I. Zhuravski prize of the St. Petersburg Ways of Communication Institute. He went to St. Petersburg where he worked as a lecturer and then a Professor in the Electrotechnical Institute and the St. Petersburg Institute of the Railways (1911-1917). During that time he developed the theory of elasticity and the theory of beam deflection, and continued to study buckling. After the Armed Forces of South Russia of general Denikin had taken Kiev in 1919, Timoshenko moved. In 1922 Timoshenko moved to the United States where he worked for the Westinghouse Electric Corporation from 1923 to 1927, after which he became a faculty professor in the University of Michigan where he created the first bachelor's and doctoral programs in engineering mechanics. His textbooks have been published in 36 languages. From 1936 onward he was a professor at Stanford University. In 1957 ASME established a medal named after Stephen Timoshenko; he became its first recipient. The Timoshenko Medal honors Stephen P. Timoshenko as the world-renowned authority in the field of mechanical engineering and it commemorates his contributions as author and teacher. The Timoshenko Medal is given annually for distinguished contributions in applied mechanics.John Moyes Lessells was born on February 5, 1888 in Dunfermline, Scotland.
