We propose a design strategy for creating origami-like mechanical metamaterials with diverse non-linear properties and capable of remote actuation. The proposed triangulated cylindrical origami (TCO)-inspired enable the highly desirable strain-softening/hardening snap-through behaviors via multi-material deformable hinge design. Moreover, we couple these novel TCO origami-inspired transformative ability hard-magnetic active materials, allowing untethered shape- property-actuation in developed metamaterials. develop mathematical modeling framework metamaterials, building on approximating hinges as combination longitudinal rotational springs. validate accuracy approach by comparing analytically predicted compressive response unit cell structure corresponding numerical experimental results. Using framework, investigate magnetic field-induced large deformation superimposed solitary wave propagation metamaterial system. show that allows us to tune key characteristics enabled waves, including their characteristic width amplitude. readily manufacturable systems paves path practical engineering applications. Our studies also underscore potential magneto-mechanical interaction reconfigurable superior elastic properties.

In the finite magnetoelastic deformation context, Zeeman magnetic energy on its own is found to be inconsistent with general theory of nonlinear magnetoelasticity. An appropriate additional term, depending definition reference configuration magnetization, used modify total confer consistency. particular, this confirms that Cauchy stress tensor symmetric, in contrast recent conclusions literature where was utilized.

Propagation of the Fundamental Lamb Modes in Strain Stiffened Hard-Magnetic Soft Plates

Journal of Applied Mechanics, Год журнала: 2024, Номер 91(6)

Опубликована: Фев. 19, 2024

Abstract This study focuses on investigating hard-magnetic soft materials, characterized by magnetoactive polymers containing magnetically polarized particles as fillers. The research utilizes the Gent model of hyperelasticity to analyze propagation Lamb waves in a induced deformed compressible plate. In this investigation, we explore both finite deformations and incremental wave nonlinear materials. main objective is formulate elastic tensor relevant equations within framework Lagrangian space. To assess dispersion characteristics guided wave, introduces discusses an extension semi-analytical element (SAFE) method. Using numerical approach, further examines effects magnetic flux densities its orientation with respect direction fundamental modes. starts examining limiting case neo-Hookean material explain such inherent dependencies. These dependencies are then emphasized including strain-stiffening effect that describes. findings reveal presence threshold applied flux, beyond which Gent-type may undergo snap-through instability, resulting changes symmetric mode.

Abstract Hard-magnetic soft materials (hMSMs) are smart composites that consist of a mechanically polymer matrix impregnated with hard magnetic filler particles. This dual-phase composition renders them exceptional magneto-mechanical properties allow to undergo large reversible deformations under the influence external fields. Over last decade, hMSMs have found extensive applications in robotics, adaptive structures, and biomedical devices. However, despite their widespread utility, they pose considerable challenges fabrication characterization owing multi-phase nature, miniature length scales, nonlinear material behavior. Although noteworthy attempts been made understand coupled rudimentary concepts inter-phase interactions give rise mechanical nonlinearity remain insufficiently understood, this impedes further advancements. holistic review addresses these standalone bridges gaps by providing thorough examination myriad techniques, applications, experimental, modeling approaches. Specifically, presents wide spectrum ranging from traditional molding cutting-edge four-dimensional printing, unbounded prospects diverse fields research. The covers various approaches, including continuum frameworks encompassing phenomenological homogenization models, as well microstructural models. Additionally, it emerging techniques like machine learning-based context hMSMs. Finally, expansive landscape promising systems is provided for better understanding prospective
