Deformable solids have a particularly complex character; mathematical modeling is not always simple and often leads to inextricable difficulties of computation. One of the simplest mathematical models and, at the same time, the most used model, is that of the elastic body - especially the linear one. But, notwithstanding its simplicity, even this model of a real body may lead to great difficulties of computation.
The practical importance of a work about the theory of elasticity, which is also an introduction to the mechanics of deformable solids, consists of the use of scientific methods of computation in a domain in which simplified methods are still used.
This treatise takes into account the consideration made above, with special attention to the theoretical study of the state of strain and stress of a deformable solid. The book draws on the known specialized literature, as well as the original results of the author and his 50+ years experience as Professor of Mechanics and Elasticity at the University of Bucharest. The construction of mathematical models is made by treating geometry and kinematics of deformation, mechanics of stresses and constitutive laws. Elastic, plastic and viscous properties are thus put in evidence and the corresponding theories are developed. Space problems are treated and various particular cases are taken into consideration. New solutions for boundary value problems of finite and infinite domains are given and a general theory of concentrated loads is built. Anisotropic and non-homogeneous bodies are studied as well. Cosserat type bodies are also modeled. The connection with thermal and viscous phenomena will be considered too.
Audience: researchers in applied mathematics, mechanical and civil engineering.
Petre P. Teodorescu, 1929, is currently a consulting professor at the Faculty of Mathematics, University of Bucharest, Romania, where he also received his scientific education. During his academic career he was awarded the "Gh. Titeica" Prize of the Romanian Academy in 1966, 20 scientific grants and several honorary titles, and he also became Member of the Academy of Technical Sciences of Romania in 1999, and President of the Romanian section of GAMM (Gesellschaft fur Angewandte Mathematik und Mechanik) in 2002. He is a member of the American Mathematical Society and the European Mechanics Society as well as various other societies, and served on the editorial boards of Mechanics Research, Meccanica, and Letters in Applied and Engineering Sciences, among others. He has a long history of teaching activities, research, participation and organization of international conferences and scientific writing, with 255 journal papers to his name. His fields of expertise encompass Mechanics of Deformable Solids, Mathematical Methods of Calculus in Mechanics. With Springer Professor Teodorescu published the 3-volume work Mechanical Systems, Classical Models and co-authored two further titles.
