Syllabus mentioned in ERP
Basic modes of fracture, Griffith theory of brittle fracture, Irwin’s modifications for elastic-plastic materials, theories of linear elastic fracture mechanics, stress intensity factors, fracture toughness testing. Crack-tip plasticity and elasto-plastic fracture mechanics in metals. Mixed mode problems and evaluation of critical fracture parameters. Classical theoretical analyses based on complex stress function approaches. Computational fracture mechanics: SERR evaluations, J-Integral methods. Fatigue damage theories, fatigue test, endurance limit, fatigue fracture under combined loading, fatigue controlling factors, effect of stress concentrations, notch sensitivity, cumulative fatigue damage concepts. Creep fracture: creep-stresstime temperature relations, creep relaxation theories; creep in tension, bending, torsion and combined loading; creep buckling; creep in piping and high temperature pressure vessel systems.
