The present work strives to explore some qualitative analysis for the governing equation describing dynamic response of a piezoelectro-magnetic circular rod. As result integrability study governed equation, which furnishes valuable insights into its structure, solutions, and applications in various fields, we apply well-known Ablowitz–Ramani–Segur (ARS) algorithm prove non-integrability Painlevé sense. theory planar integrable systems is applied bifurcation solutions based on values rod material properties.

Chiral metamaterials, lacking centrosymmetry at the unit cell level, exhibit acoustic activity and are promising candidates for elastic‐wave manipulation. For numerical analysis, their complex structures require substantial computational resources, making wave propagation simulations of chiral metamaterials challenging. Well‐known homogenization methods, based on classical Cauchy continuum, fail to predict in metamaterials. This failure is due use even‐order material property tensors, which only account centrosymmetric behavior, overlooking intrinsic chirality microrotations essential tailored responses. In this study, augmented asymptotic couple‐stress theory (CST) employed. The governing partial differential equations involve second‐ fourth‐order spatial derivatives displacements. Herein, solution demonstrated both analytically a closed form low‐frequency range numerically using COMSOL Multiphysics, employing equation‐based module. homogenized results verified by comparing with band diagram polarization rotation analysis derived from conducting computationally expensive detailed modelling. analytical closely aligned predictions modelling domain, indicating that CST offers an efficient accurate method predicting rationally designed

Abstract The present study deals with shear wave propagation in a fully coupled Magneto-Electro-Elastic (MEE) multi-laminated periodic structure having non-uniform and imperfect interfaces. As solution methodology, we applied more general low-frequency dynamic asymptotic homogenization technique where the will be single-frequency dependent obtained results generalize those published Chaki Bravo-Castillero (Compos Struct 322:117410, 2023b) perfect contact case was studied. Effective homogenized dispersive equations of motion second- fourth-order approximations, also known as “Good” Boussinesq elastic case, are derived. Local problems, closed-form expression dispersion second approximations solutions first local problems second-order approximation for tri-laminated MEE have been validated laminates case. effect contact, angle incidence, unit cell size, volume fraction ME-coupling on is illustrated through graphs. curve serves highlight work.
