The sixth edition is updated and reorganized, each of the topics is thoroughly developed from fundamental principles. The assumptions, applicability and limitations of the methods are clearly discussed. Includes such advanced subjects as plasticity, creep, fracture, mechanics, flat plates, high cycle fatigue, contact stresses and finite elements. Due to the widespread use of the metric system, si units are used throughout. � introduction. � theories of stress and strain. � linear stress-strain-temperature relations. � inelastic material behavior. � applications of energy methods. � torsion. � bending of straight beams. � shear center for thin-wall beam cross sections. � curved beams. � beams of elastic foundations. � the thick-wall cylinder. � elastic and inelastic stability of columns. � flat plates. � stress concentrations. � fracture mechanics. � fatigue: progressive fracture. � contact stresses. � creep: time-dependent deformation.
