Performance investigation of high-proportion Saudi-fly-ash-based concrete
Mugahed, Amran; Soto, Mariantonieta Gutierrez; Alyousef, Rayed; El-Zeadani, Mohamed; Alabduljabbar, Hisham; Aune, Vegard (Peer reviewed; Journal article, 2020)Approximately 544 million tonnes of fly ash (FA) are generated annually worldwide, 80% of which is disposed of in landfills. Thus, using FA as a replacement for cement has turned out to be popular in construction industries ... -
Performance of perforated aluminium plates subjected to blast loading
Sørbøl, Jørgen (Master thesis, 2020)Hovedmålet med denne oppgave er å undersøke oppførselen til tynne deformerbare aluminiumsplater, med og uten perforerte hull, utsatt for eksplosjonslast. Arbeidet består av en omfattende eksperimentell undersøkelse av ... -
Performance of thin blast-loaded steel plates after ballistic impact from small-arms projectiles
Elveli, Benjamin Stavnar; Berstad, Torodd; Børvik, Tore; Aune, Vegard (Peer reviewed; Journal article, 2023)It is known from real blast-load events that the combined effect of fragment impact and blast loading is more severe than the effect of the blast loading alone. The present study investigates this effect by comparing the ... -
Plated aluminium structures exposed to extreme pressure loads
Celius, Odin; Knoph, Magnus Leirvik (Master thesis, 2020)Begrepet ekstreme trykkbelastninger beskriver trykklaster av høy størrelsesorden, kort varighet og ikke-lineær fordeling i tid og rom. Ekstreme trykkbelastninger er kritiske for designet av platestrukturer i en rekke av ... -
