A C0 interior penalty Finite Element Method for flexoelectricity
Ventura, Jordi; Codony Gisbert, David; Fernández Méndez, Sonia (2021-09)
Article
Accés obertWe propose a C0 Interior Penalty Method (C0-IPM) for the computational modelling of flexoelectricity, with application also to strain gradient elasticity, as a simplified case. Standard high-order C0 finite element ... -
A Cº interior penalty method for 4th order PDEs
Fojo, Dani; Codony Gisbert, David; Fernández Méndez, Sonia (2020-12-01)
Article
Accés obertA method to solve 4th-order PDEs using the Finite Element Method (FEM) with standard C0 elements is derived and studied. It is based on a special weak form accounting for the discontinuous derivatives of the approximation ... -

Geometrically polarized architected dielectrics with apparent piezoelectricity
Mocci, Alice; Barceló Mercader, Jordi; Codony Gisbert, David; Arias Vicente, Irene (2021-12)
Article
Accés obertThrough the suitable geometry of a repeating unit, a metamaterial can exhibit a property not present in the base material. Here, we propose a class of low area-fraction, bending-dominated metamaterials that exhibit apparent ... -
Mathematical and computational modeling of flexoelectricity
