Mechanics and Physics of brittle to ductile transitions in fracture
Article Abstract:
The mechanisms of brittle-to-ductile transition of fracture in intrinsically brittle crystalline solids such as structural steel is of great technological interest for a long time. A renewed level of interest has resulted in a number of fundamental studies of both experimental nature and modeling of crack-tip response which demonstrated a remarkable connection of atomic atomic level processes at tips of cleavage cracks and macroscopic fracture transitions.

Effect of loading rate on fracture morphology in high strength ductile steel
Article Abstract:
Under static and dynamic loading conditions three-point bend and one-point bend configurations were used to conduct fracture experiments in high-strength ductile steel. The changes in the failure mechanisms were understood as a function of loading rate, by combining the results obtained from fracture experiments and microstructural characterization of the fractured surfaces.

Viscoplastic constitutive modeling of anisotropic damage under nonproportional loading
Article Abstract:
A viscoplastic constitutive modeling of anisotropic damage under nonproportional loading is developed for the prediction of Forming Limit Curve (FLC). The model is utilized to determine the FLC of aluminum 6111-T4 sheet alloy.
