Mechanics of Solids, Volume II, builds on the foundations of Volume I to offer a unified, advanced treatment of strength of materials and theory of elasticity. This volume develops each topic through the fundamental equations of 3D linear elasticity, followed by engineering formulations, clearly outlining their assumptions, applicability, and limitations. Covering axisymmetric loading, torsion with warping, plane stress and plane strain, stress concentration, stress intensity, 3D potential solutions, contact mechanics, fracture mechanics, anisotropic elasticity, and wave propagation, the book provides rigorous, yet concise explanations supported by practical examples and thoughtfully designed problems. Catering to senior undergraduate students, graduate students, researchers, and practicing engineers, this volume serves as an essential resource for deepening understanding of advanced solid mechanics and for bridging the gap between engineering theory and elasticity-based formulations.
