A phase-field model for microbiologically influenced corrosion
S. Kovacevic, E. Martínez-Pañeda
A phase-field-based reaction-diffusion corrosion model is developed to predict microbially influenced corrosion (MIC) in metal alloys, with a focus on anaerobic conditions and sulf…
Can dents and gouges compromise the structural integrity of hydrogen transport pipelines?
R. Das, B. Bezensek, E. Martínez-Pañeda
Repurposing natural gas pipelines for hydrogen transport requires understanding how external defects, like dents and gouges, affect structural integrity under H exposure. To ad…
Coupled thermo-chemo-mechanical phase field-based modelling of hydrogen-assisted cracking in girth welds
L. Castro, Y. Navidtehrani. C. Betegón, E. Martínez-Pañeda
A new computational framework is presented to predict the structural integrity of welds in hydrogen transmission pipelines. The framework combines: (i) a thermo-mechanical weld pro…
A neural network machine-learning approach for characterising hydrogen trapping parameters from TDS experiments
N. Marrani, T. Hageman, E. Martínez-Pañeda
The hydrogen trapping behaviour of metallic alloys is generally characterised using Thermal Desorption Spectroscopy (TDS). However, as an indirect method, extracting key parameters…
A generalised framework for phase field-based modelling of coupled problems: application to thermo-mechanical fracture, hydraulic fracture, hydrogen embrittlement and corrosion
Y. Navidtehrani, C. Betegón, E. Martínez-Pañeda
We present a novel, generalised formulation to treat coupled structural integrity problems by combining phase field and multi-physics modelling. The approach exploits the versatili…
Pull-off strength of mushroom-shaped fibrils adhered to rigid substrates
C. Betegón, C. Rodríguez, E. Martínez-Pañeda +1
The exceptional adhesion properties of biological fibrillar structures -- such as those found in geckos -- have inspired the development of synthetic adhesive surfaces. Among these…
