Localization and fracture criteria
Article Abstract:
Localization studies of porous cylinders under axial compression show that failure will occur in a plane perpendicular to the r-theta plane, making an angle of roughly 48 degrees with r axis. The failure is due to a shear band caused by the softening of the material in the presence of voids. The maximum shear stress at failure is approximately constant, and the Hoffmanner's criterion is reasonable. The variables representing damages are not constant at failures. Other models are also discussed.

An experimental study evaluating macroscopic cavity interactions as a model of microvoid ductility
Article Abstract:
The interactions between macroscopic cavities were examined empirically. Cavity-centered fracture surface features and ligament thinning which are usually found around and between microvoids on ductile fracture surfaces were investigated. Findings indicated the two specimens that best produced the required features. The load-displacement results of these experiments also demonstrated the effect of cavity geometry on the net strength and ductility of the array system.
