Internal Tides and the Spread of River Plumes in the Trondheim Fjord
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:56, Doctoral thesis, 2004)The Trondheim Fjord receives a substantial amount of freshwater during the year, with a mean runoff of 725 m3s-1 and a spring flood maximum of up to 6430 m3s-1. How this freshwater spreads and mixes with the ambient presents ... -
Investigations of some material properties for structural analysis of LECA masonry
(Dr. ingeniøravhandling, 0809-103X; 2001:9, Doctoral thesis, 2001)Masonry made from Light Expanded Clay Aggregate (LECA) concrete blocks is by far the most popular manufactured masonry in Norway. LECA is a lightweight aggregate (LWA). The main objective of this study is to expand the ... -
Kollektivtransportmodellering: Kan eksisterende transportmodeller utvikles slik at de blir mer egnet til analyser av kollektivtransport?
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:224, Doctoral thesis, 2005)Kan eksisterende transportmodeller utvikles slik at de blir mer egnet til analyser av kollektivtransporten? Ja, det kan de, viser arbeidet i denne avhandlingen. En rekke egenskaper ved dagens modeller er studert, primært ... -
Linking advanced fracture models to structural analysis
(Dr. ingeniøravhandling, 0809-103X; 2001:78, Doctoral thesis, 2001)In this study a link between local material models and structural analysis is outlined. An ”ad hoc” element formulation is used in order to connect complex material models to the finite element framework used for structural ... -
