Journal Article
Andrade, H., Trevelyan, J., & Leonel, E. (2023). Direct evaluation of stress intensity factors and T-stress for bimaterial interface cracks using the extended isogeometric boundary element method. Theoretical and Applied Fracture Mechanics, 127, Article 104091. https://doi.org/10.1016/j.tafmec.2023.104091

This paper presents a new extended isogeometric boundary element method (XIGABEM) for the analysis of cracks in two-dimensional bimaterial interfaces. The classical NURBS approximations used in isogeometric formulations are augmented with functions b...

The solution of the wave-diffusion equation by a Caputo derivative-based Finite Element Method formulation (2023)
Journal Article
Correa, R., Carrer, J., Solheid, B., Trevelyan, J., Arndt, M., & Machado, R. (2023). The solution of the wave-diffusion equation by a Caputo derivative-based Finite Element Method formulation. Journal of the Brazilian Society of Mechanical Sciences and Engineering, 45(5), Article 261. https://doi.org/10.1007/s40430-023-04175-0

A Finite Element Method approach is presented for the solution of the two-dimensional wave-diffusion equation. The fractional time derivative is considered as a Caputo derivative. Houbolt and Newmark methods are employed for the time-marching process... Read More about The solution of the wave-diffusion equation by a Caputo derivative-based Finite Element Method formulation.

An isogeometric boundary element formulation for stress concentration problems in couple stress elasticity (2023)
Journal Article
Hattori, G., Trevelyan, J., & Gourgiotis, P. (2023). An isogeometric boundary element formulation for stress concentration problems in couple stress elasticity. Computer Methods in Applied Mechanics and Engineering, 407, Article 115932. https://doi.org/10.1016/j.cma.2023.115932

An isogeometric boundary element method (IGABEM) is developed for the analysis of two-dimensional linear and isotropic elastic bodies governed by the couple stress theory. This theory is the simplest generalised continuum theory that can eectively mo...
