Download or read book Multi-Scale Modeling of Deformation of a Magnesium Alloy written by Nitin Chandola and published by . This book was released on 2014 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroscopic model. However, if it is assumed that the plastic deformation is fully accommodated by crystallographic slip, the predicted axial strains are very close to that obtained with Hill (1948) criterion, which largely underestimates the measured axial strains in one orientation and cannot capture at all the development of axial strains in torsion along the normal direction. For the first time, the unusual features of the buckling behavior of Mg AZ31 were explained. Furthermore, it was clearly demonstrated that the critical stress, the level of axial strain at buckling, and the deformed profiles can be predicted with accuracy.
