The square plates had an exposed area of ... -
Experimental tests and numerical simulations of ballistic impact on laminated glass
Osnes, Karoline; Holmen, Jens Kristian; Grue, Tormod Håøy; Børvik, Tore (Peer reviewed; Journal article, 2021)In this study, we investigate double-laminated glass plates under ballistic impact through experimental tests and numerical simulations. The experimental tests are used to determine the ballistic limit velocity and curve ... -
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 (Peer reviewed; Journal article, 2022)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. ... -
Experiments and simulations of empty and sand-filled aluminum alloy panels subjected to ballistic impact
Holmen, Jens Kristian; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2017)In this study, we use a discrete particle method in combination with finite element analysis to describe the interaction between structures and granular media during ballistic impact. By applying a discrete particle method ... -
Finite element analysis of porous polymer coated pipelines subjected to impact
Vestrum, Ole; Langseth, Magnus; Børvik, Tore (Peer reviewed; Journal article, 2021)Subsea steel pipelines are often coated with external polymer coatings. While primarily applied for corrosion protection and thermal insulation, such coatings have been shown to contribute significantly to the energy ... -
Finite element modeling of porous polymer pipeline coating using X-ray micro computed tomography
Vestrum, Ole; Langseth, Magnus; Børvik, Tore (Journal article; Peer reviewed, 2019)Offshore pipelines are designed to sustain impact from fish trawl equipment and anchors, but due to component complexity, insulating coating solutions are often neglected in mechanical capacity estimates. In this work, ... -
