Double-layer configurations of high-strength steel plates subjected to ballistic impact: A numerical study
Smedsrud, Erik; Karlsen, Jonas (Master thesis, 2021)This thesis investigates projectile impact on double-layered high-strength steel (HSS) plates commonly used for ballistic protection of buildings. The gap between adjoining protective plates in such configurations may be ... -
Experimental Tests and Numerical Simulations on the Ballistic Impact Response of a Highly Inhomogeneous Aluminium Foam
Brekken, Kristoffer Aune; Vestrum, Ole; Dey, Sumita; Reyes, Aase; Børvik, Tore (Materials;Volume 15 / Issue 13, Peer reviewed; Journal article, 2022-07-01)A sandwich structure is a composite material consisting of thin skins encapsulating a cellular core. Such structures have proven to be excellent energy absorbents and are frequently found in various types of protection. ... -
On the ballistic perforation resistance of a sandwich structure with aluminium skins and aluminium foam core
Brekken, Kristoffer Aune; Bakk, Maria S.; Dey, Sumita; Berstad, Torodd; Reyes, Aase; Børvik, Tore (Peer reviewed; Journal article, 2023)Sandwich structures have proven to be excellent energy absorbents and are found in various protective solutions. In this study, an inhomogeneous aluminium foam was used as core material in a sandwich panel with skins of ...
