With the high rates at which plastic deformations occur in ballistic impacts, failure by adiabatic shear localizations often plays prominent role effecting the performance of both the attacking projectile and the defending armor materials. Adiabatic shear failure has traditionally been viewed as a negative…
High speed machining (HSM) is an advanced machining technology with great future potential. It is widely oberved that the continuous smooth chip flow breaks down and serrated chip flow begins to form with cutting speed increasing, which is found to be ascribed to a…
Mg alloys have high potential for use in lightweight structural components, especially in automotive applications, due to their low density and high specific strength. Many studies on Mg alloys for protection applications have been conducted, focusing on achieving high dynamic and spall strengths. However,…
Mg and its alloys have great potential as structural materials because of their light weight, decent strength and ductility, and rich resource on the earth. They are arguably the lightest structural materials developed so far and have found some niche applications especially in aerospace…
One of the most important issues related to dynamic shear localization is the correlation among the stress collapse, temperature elevation and adiabatic shear band (ASB) formation. In this work, the adiabatic shear failure process of pure titanium was investigated by dynamic shear-compression tests synchronically…
Computationally inexpensive particle-based coarse-grained (CG) models are crucial for simulations of mesoscopically slow cooperative phenomena such as plastic deformations in solids. To date, no pairwise models have been reported in the literature that are able to reproduce the space group symmetry of the molecular…
