Phase-field modelling of brittle fracture in thin shell elements based on the MITC4+ approach (2020)
Journal Article
Pillai, U., Triantafyllou, S. P., Ashcroft, I., Essa, Y., & de la Escalera, F. M. (2020). Phase-field modelling of brittle fracture in thin shell elements based on the MITC4+ approach. Computational Mechanics, 65, 1413–1432. https://doi.org/10.1007/s00466-020-01827-z

We present a phase field based MITC4+ shell element formulation to simulate fracture propagation in thin shell structures. The employed MITC4+ approach renders the element shear- and membrane- locking free, hence providing high-fidelity fracture simu...

Discrete and phase field methods for linear elastic fracture mechanics: a comparative study and state-of-the-art review. Applied Sciences, 9(12), Article 2436. https://doi.org/10.3390/app9122436

© 2019 by the authors. Three alternative approaches, namely the extended/generalized finite element method (XFEM/GFEM), the scaled boundary finite element method (SBFEM) and phase field methods, are surveyed and compared in the context of linear elas...

Challenges of Hybrid Laminar Flow Control (HLFC) in Aircraft Design and Manufacturing (2018)
Presentation / Conference
Martin De La Escalera, F., Essa, Y., Castello, M. Á., Pillai, U., Chiminelli, A., Lizaranzu, M., & Maimi, P. (2018, June). Challenges of Hybrid Laminar Flow Control (HLFC) in Aircraft Design and Manufacturing. Paper presented at ECCM18 - 18th European Conference on Composite Materials, Athens, Greece

The purpose of this paper is to describe barriers and efforts made in the design of an aircraft in terms of reducing pollution emission into the atmosphere throughout the structural optimization of the aircraft's airfoils. In particular, the present... Read More about Challenges of Hybrid Laminar Flow Control (HLFC) in Aircraft Design and Manufacturing.
