Simulation and Experimental Tests of Ballistic Impact on Composite Laminate Armor
Advances in Materials Science and Engineering, 2018 This paper presents the experimental testing and simulation results of ballistic impact tests on laminated armor samples that consist of three layers of different materials: fiber-cement, Kevlar fabric, and steel. In experimental tests, a 9 mm FMJ bullet

Nondestructive Testing of Welded Composite Metal Foams
Advanced Engineering Materials, EarlyView.X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.
