WebAug 24, 2024 · Mayeur and McDowell [ 15] constructed a three-dimensional crystal plasticity model for Ti-6Al-4V with lamellar colonies of α and β. These colonies were homogenized using an isostress assumption to avoid the high number of finite elements needed to resolve the deformation in the small scale β layers. WebSep 4, 2015 · Defects in materials are usually classified as point defects, linear defects (dislocations), and planar defects. Planar defects include the planar surface of …
