Casadei, Folco; Aune, Vegard; Valsamos, Georgios; Larcher, Martin (EUR;, Research report, 2016)This short note presents the updating of element thickness due to large membrane strains recently introduced in some shell elements (Q4GS and T3GS) of the EUROPLEXUS code (EPX). -
Aluminium plates with pre-formed slits subjected to blast loading
Granum, Henrik; Aune, Vegard; Børvik, Tore; Hopperstad, Odd Sture (Chapter, 2018)The dynamic response of thin, perforated aluminium plates subjected to blast loading was studied both experimentally and numerically. Two different blast intensities were used and the plates were pre-cut with four horizontal ... -
Aluminum structures exposed to blast loading
Hustad, Tore Andre; Lindland, Andreas Lyngtveit (Master thesis, 2014)Design of blast resistance in structures is an important aspect in modern society. Plated structures are used in a lot of constructions that can be especially vulnerable to explosions. This includes e.g. protective, offshore ... -
Aspects of fluid-structure interaction on the dynamic response of blast-loaded metallic plates
Aune, Vegard; Valsamos, Georgios; Casadei, Folco; Børvik, Tore (Chapter, 2019)This work presents results from an experimental and numerical investigation on the influence of fluid-structure interaction (FSI) on the dynamic response of thin steel plates subjected to blast loading. The loading was ... -
Behaviour and Modelling of Flexible Structures Subjected to Blast Loading
Aune, Vegard (Doctoral theses at NTNU;2017:101, Doctoral thesis, 2017)The last two decades have seen a significant increase in the research activity on blast-loaded structures. This is to a large extent related to the increased threat of deliberate use of high explosives against civilian ... -
Behaviour of plated structures subjected to blast loading
Aune, Vegard; Børvik, Tore; Langseth, Magnus (Journal article; Peer reviewed, 2015)An experimental investigation using a new shock tube facility to study blast-load effects on thin aluminium plates is presented. The shock tube is designed to expose materials and structures to extreme loading conditions, ... -
Behaviour, modelling and simulation of thin steel plates subjected to combined blast and impact loading
Elveli, Benjamin Stavnar (Doctoral thesis, 2022)This thesis studies the effects of combined fragment impact and blast loading on thin steel plates. It is here assumed that the fragments strike before the arrival of the blast wave. The fragments are represented through ... -
Blast Loaded Aluminium Plates: Experiments and numerical simulations
Melby, Emil Arne; Eide, Hilde Olaug Stakvik (Master thesis, 2013)Light and flexible protective constructions in aluminium could be subjected to a blast load. In this thesis the effect of blast loading on aluminium plates of the type 1050A ? H14 was studied through experiments and numerical ... -
Blast-load response of thin steel plates after ballistic impact from small-arms projectiles
Elveli, Benjamin Stavnar; Børvik, Tore; Aune, Vegard (Chapter, 2019)This paper investigates the dynamic response of 0.8 mm thick steel plates exposed to a combination of ballistic impact and blast loading. Two different materials, i.e., a medium-strength (Docol 600DL) steel and a high-strength ... -
Deep learning-based analysis to identify fluid-structure interaction effects during the response of blast-loaded plates
Lomazzi, Luca; Morin, David Didier; Cadini, Francesco; Manes, Andrea; Aune, Vegard (Peer reviewed; Journal article, 2023)Blast events within urban areas in recent decades necessitate that protective design is no longer reserved for military installations. Modern civil infrastructure composed of light-weight, flexible materials has introduced ... -
Description of the elasto-plastic material routine SGDI
Casadei, Folco; Aune, Vegard; Valsamos, Georgios; Larcher, Martin (EUR;, Research report, 2015)We describe the FORTRAN subroutine SGDI for rate-independent deviatoric plasticity with von Mises yield criterion and isotropic hardening, which corresponds to the VM23 material type in the EUROPLEXUS code (abbreviated as ... -
Docol 600 DL Steel Plates Subjected to Blast Loading: Numerical Simulations and Experimental Validation
Heggelund, Solveig (Master thesis, 2014)The main objective in this thesis is to further investigate the accuracy of the accumulated blast impulse and plate response employing this method, and comparing the results with performed experiments. Experiments were ... -
