This bestselling text/reference provides a comprehensive treatment of the fundamentals of fracture mechanics it presents theoretical background as well as practical applications, and it integrates materials science with solid mechanics. Fracture mechanics when a flaw is found in a reactor pressure vessel, piping, or other nuclear plant component, fracture mechanics calculations are used to analyze and predict flaw behavior, including crack growth rates and critical crack sizes. Fracture mechanics 2a through-thickness crack θ r near the crack tip, if behavior is elastic, stresses (for r small) look like ( ) 2 kgi r θ σ π ≅ ki is the stress intensity factor for the crack in an opening mode the dimension of the stress intensity is stress length.
Steven holzner is the award-winning author of more than 100 books, including physics for dummies he did his undergrad. Fracture mechanics is the field of mechanics concerned with the study of the propagation of cracks in materials it uses methods of analytical solid mechanics to calculate the driving force on a crack and those of experimental solid mechanics to characterize the material's resistance to fracture.
