A numerical study of isotropic and anisotropic constitutive models with relevance to healthy and unhealthy cerebral arterial tissues

Alfio Quarteroni, Luca Dede', Paolo Tricerri

This paper presents an analysis of hyperelastic constitutive models for continuous bodies both from a modeling and numerical point of view. Contributions are made within the context of finite element numerical simulations. Numerical results with relevance ...

Exciton hopping probed by picosecond time-resolved cathodoluminescence

Benoît Marie Joseph Deveaud, Jean-Daniel Ganière, Gwénolé Jean Jacopin, Mehran Shahmohammadi

The exciton transport is studied in high quality ZnO microwires using time resolved cathodoluminescence. Owing to the available picosecond temporal and nanometer spatial resolution, a direct estimation of the exciton average speed has been measured. When r ...

Breaking of macroscopic centric symmetry in paraelectric phases of ferroelectric materials and implications for flexoelectricity

Dragan Damjanovic, Alberto Biancoli

A centrosymmetric stress cannot induce a polar response in centric materials; piezoelectricity is, for example, possible only in non-centrosymmetric structures. An exception is meta-materials with shape asymmetry, which may be polarized by stress even when ...

The dynamics of a capsule in a wall-bounded oscillating shear flow

Lailai Zhu

The motion of an initially spherical capsule in a wall-bounded oscillating shear flow is investigated via an accelerated boundary integral implementation. The neo-Hookean model is used as the constitutive law of the capsule membrane. The maximum wall-norma ...
