A fracture-propagation-control model for pipelines transporting CO2-rich mixtures including a new method for material-model calibration

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1465640

This work considers a predictive numerical modelling approach for fracture-propagation control in CO2-transport pipelines, an area where current engineering tools do not work. Fluid-structure interaction model simulations are compared with three published medium-scale crack-arrest experiments with C...

Latent hardening and plastic anisotropy evolution in AA6060 aluminium alloy

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1296125

The crystal plasticity theory predicts that hardening on a particular slip system and its corresponding work-hardening rate will depend on the slip activity on both this slip system and all others. The exact form of this dependence is defined by the latent hardening description in form of the latent...

Deformation and strain localization in polycrystals with plastically heterogeneous grains

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1409649

A model of a polycrystalline material is studied, where each grain consists of several zones with different plastic properties. The size and configuration of the zones as well as their properties are mimicking the situation inside the crystals of artificially aged Al alloys with precipitate free zon...

Fracture propagation control in CO2 pipelines: Validation of a coupled fluid-structure model

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1356621

Existing engineering methods to ensure fracture propagation control in natural-gas transmission pipelines have been shown to be non-applicable when dense-phase CO2 is transported. To overcome this, a coupled fluid-structure interaction model has been developed. It consists of a homegeneous equlibriu...

A microstructure-based yield stress and work-hardening model for textured 6xxx aluminium alloys

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1357007

The plastic properties of an aluminium alloy are defined by its microstructure. The most important factors are the presence of alloying elements in the form of solid solution and precipitates of various sizes, and the crystallographic texture. A nanoscale model that predicts the work-hardening curve...

Texture gradients and strain localisation in extruded aluminium profile

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1400473

Through-thickness crystallographic texture gradients may develop in extruded profiles and rolled sheets of aluminium alloys. These texture gradients are often modelled using the crystal plasticity theory in order to predict strain localisation more accurately. In this work, an experimental and numer...
