A C0 interior penalty Finite Element Method for flexoelectricity
(2021-09)
Article
Open AccessWe 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
(2020-12-01)
Article
Open AccessA 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 ... -
An immersed boundary hierarchical B-spline method for flexoelectricity
(2019-09-01)
Article
Open AccessThis paper develops a computational framework with unfitted meshes to solve linear piezoelectricity and flexoelectricity electromechanical boundary value problems including strain gradient elasticity at infinitesimal ... -
C0-IPM with generalised periodicity and application to flexoelectricity-based 2D metamaterials
(2022-05-18)
Article
Restricted access - publisher's policyWe propose a methodology to solve high-order PDE boundary value problems with generalised periodicity, in the framework of the C0 interior penalty method. The method is developed for the analysis of flexoelectricity- based ... -

From physical to digital in structural engineering classrooms using digital fabrication
(2017-11)
Article
Open AccessIn this paper, a set of digital artifacts related to simple examples of structural engineering are presented. The artifacts are real-time applications and visualizations of typical problems students from the architecture, ... -
Geometrically polarized architected dielectrics with apparent piezoelectricity
(2021-12)
Article
Open AccessThrough 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
(2021-12-21)
Article
Open AccessWe first revisit the mathematical modeling of the flexoelectric effect in the context of continuum mechanics at infinitesimal deformations. We establish and clarify the relation between the different formulations, point ... -
Modeling flexoelectricity in soft dielectrics at finite deformation
(2021-01)
Article
Open AccessThis paper develops the equilibrium equations describing the flexoelectric effect in soft dielectrics under large deformations. Previous works have developed related theories using a flexoelectric coupling tensor of mixed ... -

Weak enforcement of interface continuity and generalized periodicity in high-order electromechanical problems
(John Wiley & sons, 2022-02-28)
Article
Open AccessWe present a formulation for the weak enforcement of continuity conditions atmaterialinterfacesinhigh-orderproblemsbymeansofNitsche’smethod,whichis particularly suited for unfitted discretizations. This formulation is ...
