A model for the ultrasonic detection of surface-breaking cracks by the scanning laser source technique
(2004-01)
Article
Open AccessA model for the scanning laser source (SLS) technique is presented. The SLS is a novel laser-based inspection method for the ultrasonic detection of small surface-breaking cracks. The generated ultrasonic signal is monitored ... -
A phase-field fracture model of ferroelectric materials under electro-mechanical loading
(2011)
Conference report
Restricted access - publisher's policyA phase-field model is proposed for the coupled simulation of microstructure and fracture evolution in ferroelectric materials. The model is based on energetic phase-field approaches for brittle fracture and ferroelectric ... -
A phenomenological cohesive model of ferroelectric fatigue
(2006-02)
Article
Open AccessWe develop a phenomenological model of electro-mechanical ferroelectric fatigue based on a ferroelectric cohesive law that couples mechanical displacement and electric-potential discontinuity to mechanical tractions and ... -
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 ... -

Computational evaluation of the flexoelectric effect in dielectric solids
(American Institute of Physics (AIP), 2014-09-07)
Article
Restricted access - publisher's policyFlexoelectricity is a size-dependent electromechanical mechanism coupling polarization and strain gradient. It exists in a wide variety of materials, and is most noticeable for nanoscale objects, where strain gradients are ... -
Computational homogenization of higher-order electro-mechanical materials with built-in generalized periodicity conditions
(Elsevier, 2024-04-01)
Article
Open AccessWe present a formulation for high-order generalized periodicity conditions in the context of a high-order electromechanical theory including flexoelectricity, strain gradient elasticity and gradient dielectricity, with the ... -
Conducting crack propagation driven by electric fields in ferroelectric ceramics
(2013-11)
Article
Restricted access - publisher's policyFerroelectric ceramics are susceptible to fracture under high electric fields, which are commonly generated in the vicinity of electrodes or conducting layers. In the present work, we extend a phase-field model of fracture ... -
Constructive and destructive interplay between piezoelectricity and flexoelectricity in flexural sensors and actuators
(2015)
Article
Open AccessFlexoelectricity is an electromechanical effect coupling polarization to strain gradients. It fundamentally differs from piezoelectricity because of its size-dependence and symmetry. Flexoelectricity is generally perceived ... -
Converse flexoelectricity yields large piezoresponse force microscopy signals in non-piezoelectric materials
(2019-03-20)
Article
Open AccessConverse flexoelectricity is a mechanical stress induced by an electric polarization gradient. It can appear in any material, irrespective of symmetry, whenever there is an inhomogeneous electric field distribution. This ... -
Crack initiation patterns at electrode edges in multilayer ferroelectric actuators
(2012-12)
Article

Experimental validation of large-scale simulations of dynamic fracture along weak planes
(2009-07)
Article
Open AccessA well-controlled and minimal experimental scheme for dynamic fracture along weak planes is specifically designed for the validation of large-scale simulations using cohesive finite elements. The role of the experiments ... -

Fracture toughening and toughness asymmetry induced by flexoelectricity
(2015-09-08)
Article
Restricted access - publisher's policyCracks generate the largest strain gradients that any material can withstand. Flexoelectricity (coupling between strain gradient and polarization) must therefore play an important role in fracture physics. Here we use a ...
