Course Goals / Objectives:
Obtain understanding of nature of stress and strain fields surrounding sharp crack like defects in elastic solids as characterized by the stress intensity factor, including the effects of cracked structure geometry, and limited near tip plasticity
Obtain an understanding of basic energy relationships in fracture, including the strain energy release rate and the J-integral
Obtain a basic understanding of the concepts and experimental methods for characterization of material fracture resistance through fracture toughness and related materially dependent parameters
Ability to apply a variety of crack propagation criteria for determining the critical values of the applied loading and crack length at crack propagation
Obtain a basic understanding of the mechanisms and modeling of fatigue crack growth (cyclic sub-critcal loading and crack growth)
