...Saibal Kanchan Barik; R. Ganesh Narayanan; Niranjan Sahoo Selection of flow stress models and fracture models to model sheet deformation at high strain rates is of great concern. The same is attempted in the present work during shock tube impact forming of 1-mm-thick AA 5052-H32 sheet using a rigid...

... in a commercially pure aluminum (AA1070). The effects of temperature and strain rate on the hot deformation behavior were represented by Zener–Hollomon parameter including Arrhenius term. The results show that the hardening rate and flow stress are evidently affected by both deformation temperature and strain rate...

.... Editor: Tetsuya Ohashi. 11 04 2013 07 08 2013 Accurate modeling of workpiece material behavior in machining is critical to analyze and design a process. The workpiece material behavior in the machining process involves dynamic flow stress and damage/fracture behavior, which are very...

... localizations. Several conclusions related to the width and intensity of the shear localization, considering various velocities and temperatures, are discussed. HSLA-65 DH-36 flow stress strain localization hat-shaped specimen Numerous studies on the formation of shear bands (shear...
