Size dependent nonlinear elastic scaling of multiwalled carbon nanotubes
(2008-02)
Article
Accés obertWe characterize through large-scale simulations the nonlinear elastic response of multi-walled carbon nanotubes (MWNCNTs) in torsion and bending. We identify a unified law consisting of two distinct power-law regimes in ... -
Switchable tribology of ferroelectrics
(2024-01-09)
Article
Accés obertSwitchable tribological properties of ferroelectrics offer an alternative route to visualize and control ferroelectric domains. Here, we observe the switchable friction and wear behavior of ferroelectrics using a nanoscale ... -
Thermoelastic generation of ultrasound by line-focused laser irradiation
(2003-12)
Article
Accés obertA two-dimensional theoretical model for the field generated in the thermoelastic regime by line-focused laser illumination of a homogeneous, isotropic, linearly elastic half-space is presented. The model accounts for the ... -
Three-dimensional simulation of crack propagation in ferroelectric polycrystals: Effect of combined toughening mechanisms
(2014-02-15)
Article
Accés restringit per política de l'editorialWe simulate the fracture processes of ferroelectric polycrystals in three dimensions using a phase-field model. In this model, the grain boundaries, cracks and ferroelectric domain walls are represented in a diffuse way ... -
Topology optimization of flexoelectric metamaterials with apparent piezoelectricity
(Elsevier, 2024-02-01)
Article
Accés obertThe flexoelectric effect, coupling polarization and strain gradient as well as strain and electric field gradients, is universal to dielectrics, but, as compared to piezoelectricity, it is more difficult to harness as it ... -
Transversal flexoelectric coefficient for nanostructures at finite deformations from first principles
(American Physical Society (APS), 2021-03-08)
Article
Accés obertWe present a novel formulation for calculating the transversal flexoelectric coefficient of nanostructures at finite deformations from first principles. Specifically, we introduce the concept of radial polarization to make ... -
Use of reciprocity considerations for the two-dimensional BEM analysis of wave propagation in an elastic half-space with applications to acoustic emission
(2004-04)
Article
Accés obertA simple numerical treatment of the infinite boundary in the BEM analysis of two-dimensional wave propagation problems in elastic half-spaces is proposed to avoid the spurious reflections of non-decaying Rayleigh waves ... -
Weak enforcement of interface continuity and generalized periodicity in high-order electromechanical problems
(John Wiley & sons, 2022-02-28)
Article
Accés obertWe present a formulation for the weak enforcement of continuity conditions atmaterialinterfacesinhigh-orderproblemsbymeansofNitsche’smethod,whichis particularly suited for unfitted discretizations. This formulation is ...
