Effect of flexoelectricity on elasticity characterization by nanoindentation
(Universitat Politècnica de Catalunya, 2017-06-16)
Master thesis
Open AccessFlexoelectricity is a very common phenomenon in dielectrics and is a size-dependent electromechanical mechanism coupling polarization and strain gradient. Flexoelectric effect is significant due to higher strain gradients ... -

Phase-field modeling of fracture in ferroelectric materials
(Universitat Politècnica de Catalunya, 2012-10-18)
Doctoral thesis
Open AccessThe unique electro-mechanical coupling properties of ferroelectrics make them ideal materials for use in micro-devices as sensors, actuators and transducers. Nevertheless, because of the intrinsic brittleness of ferroelectrics, ... -
Robust numerical solution of charge transport in flexophotovoltaic-based devices
(Universitat Politècnica de Catalunya, 2021-07)
Master thesis
Open AccessIn this thesis, a robust computational framework for flexophotovoltaic-based devices has been developed. First, a model for describing the flexophotovoltaic effect in flexoelectric, non-piezoelectric materials is stated. ... -
Theoretical and computational modeling of charge transport in flexo-photovoltaics
(Universitat Politècnica de Catalunya, 2020-10)
Master thesis
Open AccessIn this thesis, a model to describe the flexophotovoltaic effect is formulated by coupling the flexoelectricity equations with the drift-diffusion current equations. The resulting system of non-linear PDEs is numerically ... -
Towards a two dimensional model of surface piezoelectricity
(Universitat Politècnica de Catalunya, 2016-06-29)
Bachelor thesis
Open AccessWe want to understand the behaviour of flexoelectricity and surface piezoelectricity and distinguish them in order to go deep into the controversies of the filed. This motivate the construction of a model of continuum ... -
The variational approach to brittle fracture in materials with anisotropic surface energy and in thin sheets
(Universitat Politècnica de Catalunya, 2016-03-08)
Doctoral thesis
Open AccessFracture mechanics of brittle materials has focused on bulk materials with isotropic surface energy. In this situation different physical principles for crack path selection are very similar or even equivalent. The situation ...
