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…
Virtual failure assessment diagrams for hydrogen transmission pipelines
J. Wijnen, J. Parker, M. Gagliano +1
We combine state-of-the-art thermo-metallurgical welding process modelling with coupled diffusion-elastic-plastic phase field fracture simulations to predict the failure states of…
A phase field model for hydraulic fracture: Drucker-Prager driving force and a hybrid coupling strategy
Y. Navidtehrani, C. Betegón, J. Vallejos +1
Recent years have seen a significant interest in using phase field approaches to model hydraulic fracture, so as to optimise a process that is key to industries such as petroleum e…
On the fracture mechanics validity of small scale tests
C. Cui, L. Cupertino-Malheiros, Z. Xiong +1
There is growing interest in conducting small-scale tests to gain additional insight into the fracture behaviour of components across a wide range of materials. For example, micro-…
