Web3 Feb 2024 · While the geometrical necessary dislocation (GND) density of adiabatic shear band (ASB) and its surroundings increased significantly, the width of the ASB becomes wider as the strain rate increases, which is consistent with the theory of sub-grain rotation dynamic recrystallization model. WebAs indicated above, adiabatic shearing is a series of strain and strain rate–dependent process that includes the initiation and development of deformed band, the transformation from deformed band to transformed band (development of mixed zone), the development of the transformed band, until the crack propagating along the shear band and leading …
WebIn physics, mechanics and engineering, an adiabatic shear band is one of the many mechanisms of failure that occur in metals and other materials that are deformed at a high rate in processes such as metal forming, machining and ballistic impact. Web10 Jan 2024 · One of the most important issues related to adiabatic shear failure is the correlation among temperature elevation, adiabatic shear band (ASB) formation and the loss of load capacity of the material.
