Dynamic response of high-entropy alloys to ballistic impact

open access: yesScience Advances, 2022
High-entropy alloys (HEAs) are promising to provide effective antiballistic capability because of their superior mechanical properties. However, the twinning-active Cantor alloy is found less ballistic resistant, compared with its Mn-free companion.

Simulation on a Composite Laminate Subjected to Ballistic Impact [PDF]

open access: yesAdvances in Physics Research, 2014
A finite element model was developed to study the damage mechanisms of composite laminates under high velocity impact conditions. Modified Hashin failure criteria were used for the fiber breakage prediction. Cohesive elements were defined between two adjacent layers in the target laminate for the prediction of delamination initiation and propagation ...
