Theory and experiment for dynamics of hyperelastic plates with modal interactions

Hossein B. Khaniki et al.

Summary: This paper presents a joint experimental and theoretical approach to studying the dynamics and mass sensitivity of hyperelastic plates, including cases with modal interactions. The accuracy of simulating the nonlinear dynamics of hyperelastic plate structures under different conditions is demonstrated using both theoretical and experimental methods. Furthermore, an analysis of the nonlinear forced vibration behavior of hyperelastic plates with different internal resonances and the ability of the structure for mass sensing are discussed.

Geometrically Exact Finite Element Formulation for Tendon-Driven Continuum Robots

Xin Li et al.

Summary: Tendon-driven continuum robots achieve continuous deformations through tendon contractions. The constant curvature assumption is accurate for some cases but inaccurate for soft robots or robot-environment interactions. To model the complex deformations of continuum robots, we developed a finite element model based on the geometrically exact beam theory and demonstrated its accuracy, efficiency, and applicability through numerical examples.

Rubber elasticity of polymer networks in explicitly non-Gaussian states. Statistical mechanics and LF-NMR inquiry in hydrogel systems

Stefano A. Mezzasalma et al.

Summary: This article presents a statistical mechanics theory for rubber-like elasticity in swollen and unswollen polymer networks. The theory derives new statistical and mechanical laws and proposes a theoretical-experimental approach to identify the end-to-end length distribution in polymer networks. The study finds that different polymer networks have different end-to-end distributions, which are not Gaussian.

Tunability of Band Gaps of Programmable Hard-Magnetic Soft Material Phononic Crystals

Bo Li et al.

Summary: This paper investigates the characteristics of two-dimensional hard-magnetic soft material phononic crystals (HmSM-PnCs) under applied magnetic field, finding that the band gap can be controlled by changing the magnetic field, and the magnetic anisotropy encoding mode has a significant effect on the number of band gaps and critical magnetic field.

Thermo-mechanically coupled constitutive equations for soft elastomers with arbitrary initial states

Weiting Chen et al.

Summary: In this paper, a general framework is established to derive constitutive equations for soft elastomers with arbitrary initial states. The influences of initial stresses, initial temperature, and internal constraint on the elastic coefficients are analyzed. The proposed method fills the theoretical gap under non-isothermal circumstances and significantly improves the constitutive theory of soft materials.

On constitutive modelling of linear poroviscoelastic solids

Pei Zheng et al.

Summary: In this paper, a three-dimensional constitutive model is developed to describe the linear viscoelastic behavior of fluid-saturated porous solids. Constitutive equations for compressible and incompressible solid matrices are separately derived. Numerical results are compared with poroelastic response to demonstrate the effect of viscosity on pore pressure diffusion and solid displacement response.

Chunping Ma et al.

Summary: The combination of magnetic soft materials and magnetic shape memory polymers enables reprogrammable, untethered, fast, and reversible shape manipulation, and their enhanced multimodal shape transformation and tunable properties can be explored through multimaterial printing technology. By cooperative thermal and magnetic actuation, multiple deformation modes with distinct shape configurations can be achieved, opening up new possibilities for the fabrication of active metamaterials with tunable physical properties.

Tunability of Band Gaps in Two-Dimensional Phononic Crystals with Magnetorheological and Electrorheological Composites

Gang Zhang et al.

Summary: The combination of electric and magnetic fields can effectively adjust the band gap characteristics of phononic crystal materials. Additionally, drilling holes in the phononic crystal can move the band gaps to different frequencies, opening or closing new band gaps, offering the possibility for multi-physical field control and design optimization of the elastic wave properties of intelligent phononic crystals.

Static equilibrium configuration and nonlinear dynamics of slightly curved cantilevered pipe conveying fluid

K. Zhou et al.

Summary: The nonlinear static and dynamic behaviors of cantilevered pipes conveying fluid were explored, exhibiting interesting and sometimes unexpected results such as extremely large flow-induced static deformation of the pipe and variable critical flow velocity for flutter instability. It was demonstrated that the slightly curved pipe oscillates about the static equilibrium position and exhibits periodic motion as the preferred form of post-instability behavior within a wide range of system parameters considered.

Thermo-mechanical modeling of viscoelastic crystallizable shape memory polymers

Aayush Prasad et al.

Summary: Shape memory polymers (SMPs) are soft active materials that can retain temporary shapes and deform in response to stimuli. This paper focuses on a subclass of thermally activated SMPs, discussing their behavior and the effects of parameters such as temperature and crystallinity on nonlinear deformation and shape memory. The study shows how these parameters influence the complex thermo-mechanical behavior of SMPs.

Instability of compressible soft electroactive plates

Guozhan Xia et al.

Summary: This study investigates the formation of two-dimensional surface wrinkles in a pre-deformed compressible soft electroactive plate under two common electrical loading protocols. The symmetric wrinkles may appear prior to the antisymmetric ones, especially in charge-controlled plates. It is revealed that compressibility significantly influences the stability and non-linear response of the plate, indicating the importance of material compressibility in the design of new-generation SEA-based devices.

Constitutive modeling of magneto-viscoelastic polymers, demagnetization correction, and field-induced Poynting effect

Krishnendu Haldar

Summary: Magneto-active polymers are polymer-based composites with magnetizable micro-particles that offer tunability to stiffness and damping properties under a magnetic field. A novel free energy-based model has been proposed to derive coupled mechanical and magnetization constitutive equations. The model calibration considers demagnetization effects and the potential for field-induced reverse or negative Poynting effect in shear for magneto-active polymers.
