Theoretical analysis of the dimensionality of ultrasonic attenuation in polycrystalline materials with elongated grains

In the present work, the grain scattering-induced attenuation coefficient is obtained for longitudinal bulk waves in untextured cubic polycrystalline materials with elongated grains using proposed 2D and 3D theoretical models. These models are…

Structural mechanics

A parallel implementation of a mixed multiscale domain decomposition method applied to the magnetostatic simulation of 2D electrical machines

This article introduces a mixed domain decomposition method (DDM) designed to meet the requirements of advanced numerical optimization in electrical machines. The primary objective is to adapt the multiscale LATIN method, primarily used for…

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,…
