Offshore pipelines subjected to accidental loads, such as impacts from trawl gear or anchors, may experience large global displacements from its initial position and large local strains. The axial forces set up during ...

Foams are three dimensional cellular materials, with cell walls made up of a solid or liquid material and cells containing a gas or liquid. The solid material can be anything from a metal to a ceramic. Metallic and polymeric ...

The main objective of this thesis was to determine the impact behaviour of the high strength steel Strenx-960-Plus at room and low temperatures, and to investigate if the deformation and failure mode changed from ductile ...

Denne masteroppgaven inneholder en eksperimentell og numerisk undersøkelse av den mekaniske styrken til undersjøiske rørledninger med isolasjonslag av polymer. Målet med oppgaven var å finne ut hvordan undersjøiske ...

This work presents ongoing research on the influence of fluidstructure interaction (FSI) effects on the ductile crack growth in perforated steel plates subjected to blast loading. The FSI effects were studied numerically ...

Experimental data and numerical simulations of smooth and notched tensile tests on four different aluminium alloys are used to investigate the effect of loading path on ductile fracture. Micromechanical studies are undertaken ...

Experimental and numerical investigations are carried out to determine how thin steel plates with pre-cut defects behave under blast loading. The defects considered in this study are represented by four square holes, ...

In-plane shear tests were conducted on two extruded 6000-series aluminium alloys to investigate the influence of constituent particles on ductile fracture. The two alloys have previously been characterized and found to ...

In this study, the effect of sigma-phase precipitation in duplex stainless steel (grade 2205) pipe fittings collected from top-side process systems offshore was investigated under realistic loading conditions. This was ...
