Dynamic mechanical analysis : theoretical considerations on mechanical properties

Osnes, Harald; Thorvaldsen, Tom (2011-09-19)

English summary Dynamic mechanical analysis (DMA) is a technique used to study and characterize materials. In the test method, small test specimens, or beams, are typically subjected to harmonic, three-point bending ...
Improved discretisation and linearisation of active tension in strongly coupled cardiac electro-mechanics simulations

Sundnes, Joakim; Wall, Samuel Thomas; Osnes, Harald; Thorvaldsen, Tom; McCulloch, Andrew (2012)

Mathematical models of cardiac electro-mechanics typically consist of three tightly coupled parts: systems of ordinary differential equations describing electro-chemical reactions and cross-bridge dynamics in the muscle ...
Modelling of a thin-walled filament-wound composite cylinder using an axisymmetric approach

Thorvaldsen, Tom; Osnes, Harald (2011-03-30)

In this report, finite element analyses (FEA) are preformed for a thin-walled filament-wound composite cylinder exposed to an inner pressure load. Analyses are run for an open cylinder, as well as for a closed cylinder. ...
