A fracture-propagation-control model for pipelines transporting CO2-rich mixtures including a new method for material-model calibration
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...
Fracture-propagation control in pipelines transporting CO2-rich mixtures
Deformation and strain localization in polycrystals with plastically heterogeneous grains
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...
Understanding the forces at play when boiling CO2 drives a running pipeline fracture
Texture gradients and strain localisation in extruded aluminium profile
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...
A microstructure-based yield stress and work-hardening model for textured 6xxx aluminium alloys
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...
