Improved electro‐actuation property of dielectric elastomer composites regulated by one‐dimensional CaCu 3 Ti 4 O 12 @ TiO 2 core–shell construction

Abstract Dielectric elastomers (DEs) are typical electro‐active polymers that can achieve an electro‐actuated deformation under an applied electric field. However, obtaining a large low‐field‐actuated strain of DEs is still a key challenge, which is…

A Bloch analysis extended to weakly disordered periodic media

This paper develops an asymptotic method to predict the dispersion curves of a \rYL{weakly disordered} medium. The \rYL{disordered} coefficients of the original acoustic equation are related to periodic coefficients through a change of variables,…

Influence of arylalkyl amines on the formation of hybrid CsPbBr 3 nanocrystals via a modified LARP method

Perovskite nanocrystals have attracted much attention in the last ten years due to their different applications, especially in the photovoltaic domain and LED performance. In this large family of perovskite nanocrystals, CsPbBr3 nanocrystals are…

Ferroelectric texture of individual barium titanate nanocrystals

Ferroelectric materials display exotic polarization textures at the nanoscale that could be used to improve the energetic efficiency of electronic components. The vast majority of studies were conducted in two dimensions on thin films, that can be…

On the benefits of a multiscale strategy to model-order reduction for frictional contact problems

In this work, the efficiency of a multiscale strategy based on a domain decomposition method (DDM) for model-order reduction of friction contact problems is presented. The resolution strategy is based on the LATIN method combined with the Proper…

The Unstable Fracture of Multifilament Tows

The present paper investigates the unexpected unstable failure observed commonly on fiber tows tensile-tested under strain-controlled loading, although the force on the fibers should theoretically be relaxed under controlled strain. A model of the…
