Texts
Primary text: (readings and problems assigned from this text)
[1] S. H. Crandall, N. C. Dahl, and T. J. Lardner, An Introduction to the Mechanics of Solids, McGraw Hill, Second Ed., 1978.
Additional texts:
[2] E. P. Popov, Engineering Mechanics of Solids, PrenticeHall, Second Ed., 1998.[3] S. Govindjee, Engineering Mechanics of Deformable Solids, Oxford, 2013.
General readings:
[4] Structures or Why Things Don’t Fall Down, by J. E. Gordon: This immensely entertaining book can be read like a novel without bothering about the dry technicalities of the subject. It successfully attempts at bringing both curiosity and personal experience to our interesting subject. [5] Biomechanics, by R. M. Alexander. This and other books by the same author presents a very readable introduction to application of simple concepts from mechanics of solids to biological world.
History of Mechanics and Strength of Materials:
[6] History of Strength of Materials, by S. Timoshenko[7] Essays in the History of Mechanics, by C. A. Truesdell[8] Mechanics of Pre-industrial Technology, by B. Cotterell and J. Kamminga[9] A good summary can be found in the two-part article by Truesdell: [Part 1] [Part 2]
Further readings:
[10] Applied Mechanics of Solids by Allan Bower. The complete book is available at http://solidmechanics.org[11] The Linearized Theory of Elasticity, by W. S. Slaughter [12] Theory of Elasticity, by L. D. Landau and E. M. Lifshitz [13] Elasticity, J. R. BarberNotes, Assignments,...
