Synopsis This book covers one of the most fundamental subjects of Engineering discipline - Strength of Materials, also known as Mechanics of Materials, Mechanics of Deformable Bodies or Mechanics of Solids globally. The subject lays the ground for various Engineering subjects, ranging from Machine Design, Finite-Element Analysis, Theory of Structures, Bio-Mechanics, and Fracture Mechanics.In this book, the topics are broadly divided into two parts: Elementary Strength of Materials and Advanced Strength of Materials, thereby progressing from basic fundamentals to detailed analysis. The first eight chapters deal with basic concepts of strengths of materials such as theories of stress and strain, torsion, deflection and buckling of columns. The remaining chapters deal with the advanced topics such as advanced theories of stress and strain, energy principles, failure theories, theories of curved and continuous beams, unsymmetric or asymmetric bending.
