Francis, Amrita; Natarajan, Sundararajan; Atroshchenko, Elena; Lévy, Bruno; Bordas, Stéphane P. A. (Elsevier Ltd, 2019)In this paper, the recently proposed linearly consistent one point integration rule for the meshfree methods is extended to arbitrary polytopes. The salient feature of the proposed technique is that it requires only one ...

Videla Marió, Javier; Contreras Rojas, Felipe; Nguyen, Hoang; Atroshchenko, Elena (Elsevier, 2020)In this work, we present an eXtended Geometry Independent Field approximaTion (X-GIFT) formulation for cracked Kirchhoff-Love plates. The plate geometry is modeled by Non-Uniform Rational B-Splines (NURBS) while the solution ...

Ayala, Tomás; Videla, Javier; Anitescu, Cosmin; Atroshchenko, Elena (Elsevier, 2020)In this work, the isogeometric collocation (IGA-C) is paired with two types of enrichment: Plane Wave (PW-) and Generalized Harmonic Polynomial (GHP-) functions, to solve 2D-problems for the Helmholtz equation. A parametric ...

Videla, Javier; Anitescu, Cosmin; Khajah, Tahsin; Bordas, Stéphane P.A.; Atroshchenko, Elena (Elsevier Ltd, 2019)© 2019 Elsevier Ltd In this work, we demonstrate the application of PHT-splines for time-harmonic acoustic problems, modeled by the Helmholtz equation. Solutions of the Helmholtz equation have two features: global oscillations ...

Peralta Braz, Patricio; Ruiz García, Rafael; Natarajan, Sundaram; Atroshchenko, Elena (Elsevier, 2020)Piezo-electric energy harvesters (PEHs) are widely used to recycle waste vibrations for pow-ering small electronic devices. In this work, the performance of PEHs of non-conventional shapes is studied with the aim to optimize ...

Nguyen, Hoang X.; Atroshchenko, Elena; Ngo, Tuan; Nguyen-Xuan, H.; Vo, Thuc P. (Elsevier Ltd, 2019)In this study, the vibration behaviours of functionally graded microplates with cracks are investigated by means of a simple yet rigorous version of Mindlin's generialised continuum and the extended isogeometric analysis ...
