Fracture Of Metals Part II : Ductile Fracture
Abstract Ductile fracture results from the nucleation, growth and coalescence of cavities. Nucleation starts from inclusions. Mechanics of inclusions is used to write the nucleation criterion. The growth rate can be derived from the deformation of a cavity in a plastic or viscous material. Plastic potentials of a porous plastic solid yields the rate of increase of the porosity. Recent studies introduce anisotropy of plastic behaviour or of morphology in the analysis. Coalescence of cavities occurs by flat dimple mode or by void sheet instability. The criteria used are either a critical growth rate of porosity or a condition of plastic instability. Finite elements calculations together with the preceding criteria are used to calculate the growth of a crack.
