An extended boundary element method formulation for the direct calculation of the stress intensity factors in fully anisotropic materials (2016)
Journal Article
Hattori, G., Alatawi, I., & Trevelyan, J. (2017). An extended boundary element method formulation for the direct calculation of the stress intensity factors in fully anisotropic materials. International Journal for Numerical Methods in Engineering, 109(7), 965-981. https://doi.org/10.1002/nme.5311

We propose a formulation for linear elastic fracture mechanics (LEFM) in which the stress intensity factors (SIF) are found directly from the solution vector of an extended boundary element method (XBEM) formulation. The enrichment is embedded in the... Read More about An extended boundary element method formulation for the direct calculation of the stress intensity factors in fully anisotropic materials.

An adaptive cross approximation (ACA) for the extended boundary element method (XBEM) in anisotropic materials (2016)
Presentation / Conference Contribution

The extended boundary element method (XBEM) is a modification from the standard BEM, where enrichment functions are embedded into the BEM formulation. The results obtained with this method were seen to be accurate and stable, being especially useful...

Influence of the Main Contact Parameters in Finite Element Analysis of Elastic Bodies in Contact (2016)
Journal Article
Hattori, G., & Serpa, A. (2016). Influence of the Main Contact Parameters in Finite Element Analysis of Elastic Bodies in Contact. Key Engineering Materials, 681, 214-227. https://doi.org/10.4028/www.scientific.net/kem.681.214

One of the key issues in solving contact problems is the correct choice of the contact parameters. The contact stiffness, the penetration limit and the contact algorithm are some of the parameters that have to be adjusted. There are no methodologies...

Numerical simulation of fracking in shale rocks: current state and future approaches (2016)
Journal Article
Hattori, G., Trevelyan, J., Augarde, C., Coombs, W., & Aplin, A. (2017). Numerical simulation of fracking in shale rocks: current state and future approaches. Archives of Computational Methods in Engineering, 24(2), 281-317. https://doi.org/10.1007/s11831-016-9169-0

Extracting gas from shale rocks is one of the current engineering challenges but offers the prospect of cheap gas. Part of the development of an effective engineering solution for shale gas extraction in the future will be the availability of reliabl...
