Abstract Magnetorheological elastomers (MREs) are polymers with viscoelastic properties that can be adjusted by manipulating the magnetic field. When MREs combined reinforcing fabrics, a new category of materials known as MRE composites (MRECs) created, which not only possess characteristics but also enhance their rigidity. This study focuses on investigating supersonic aeroelastic instability rectangular sandwich plate laminated MREC core layer and functionally graded porosities face layers. Additionally, is supported an elastic foundation subjected to airflow. investigation presents improved first-order shear deformation theory, postulating parabolic distribution stresses. Consequently, transverse stresses rendered zero at surface every individual layer; thus, requirement for correction in this theory eliminated. In addition, 8-node elements implemented circumvent necessity distinct handling shear-locking. The pressure acting structure considered using piston theory. Micromechanical approaches, such Halpin‐Tsai rule mixture employed determine effective mechanical dynamic equations derived Hamilton’s principle finite element method. examines impact different fields, fiber volume fraction, factors, layering angles, geometry, boundary conditions flutter frequency.

Abstract Magnetoactive soft continuum robots (MSCRs), capable of controllable steering and navigation, hold substantial promise for healthcare applications. However, advancements in MSCRs have been hindered by a limited understanding MSCR dynamics lack effective control methods. Addressing these gaps, this study presents novel, time-dependent, computationally efficient analytical model MSCR, alongside new optimal closed-loop strategy precise high-frequency trajectory tracking. A finite element (FE) the is initially developed, with its validity confirmed through rigorous laboratory measurements. Using formulated FE model, subsequently developed to accurately predict highly nonlinear response MSCR. This operates as system switched linear models, each which reduced-order version corresponding high-order extracted from analysis. innovative approach not only maintains predictive accuracy but also significantly reduces computational demands, operating just few seconds. The results highlight that can dynamic responses while reducing load almost 80 orders magnitude compared on same simulation platform. proposed has effectively utilized develop novel using feedforward interval type-2 fractional-order fuzzy-PID method. hardware-in-the-loop experimental test finally designed demonstrate superior performance under controller.

Hard-magnetic soft materials belong to a class of the highly deformable magneto-active elastomer family smart and provide promising technology for flexible electronics, robots, functional metamaterials. When hard-magnetic actuators are driven by multiple-step input signal (Heaviside magnetic field signal), residual oscillations exhibited actuator about equilibrium positions may limit their performance accuracy in practical applications. This work aims at developing command-shaping scheme alleviating vibrations magnetically planar actuator. The control is based on balance elastic forces critical point an oscillation cycle. equation governing dynamics devised using Euler–Lagrange equation. constitutive behaviour material modeled Gent model hyperelasticity, which accounts strain-stiffening effects. dynamic response under step obtained numerically solving MATLAB ODE solver.
