Summary: In this research, the hyperelastic strain energy density function based on the exponential-logarithmic invariant is extended to the visco-hyperelastic constitutive model to accurately model the mechanical properties of rubber-like materials. A parameter identification approach using the general regression neural network (GRNN) technique is proposed for evaluating the visco-hyperelastic model. Experimental data of rubber-like materials is used to validate the proposed research scheme, and the results show good agreement between the predicted stress responses and the experimental data. The study concludes that the developed model accurately describes the mechanical behavior of rubber-like materials and the GRNN-based approach is reliable for parameter identification of complex visco-hyperelastic constitutive models.

Summary: Uniaxial and biaxial cyclic tensile tests and stress relaxation tests were conducted on EPDM material to investigate its stress-softening effect. The experimental results showed a significant Mullins effect and viscoelastic deformation in EPDM material. A visco-hyperelastic constitutive model combining pseudo-elasticity theory and viscoelastic theory was proposed, which demonstrated good agreement with experimental data and superior performance in stress-softening unloading process compared to the hyper-elastic constitutive model. This research accurately characterizes the stress-softening behavior of rubber-like materials and provides theoretical guidance for their industrial applications.

Summary: This study proposes a general 3D anisotropic visco-hyperelastic constitutive model for unidirectional continuous fiber reinforced shape memory composites. The total energy of the composites is decomposed into isotropic and anisotropic parts, with further decomposition of the matrix part into hyperelastic and visco-hyperelastic parts. A temperature-dependent energy contribution weight factor is introduced to account for the variation of energy contribution during phase transition and shape memory cycle. The proposed model is validated through thermomechanical and shape memory tests on carbon fiber reinforced composites with different fiber inclination angles.

Summary: A new anisotropic visco-hyperelastic constitutive model has been developed for predicting the time-dependent deformation response of flexible, knitted fabric-reinforced elastomer composites. This model incorporates the architecture of knitted fabrics and the hyper-viscoelastic behavior of elastomers using an invariant-based strain energy density function. The model is implemented in a commercial Finite Element Analysis (FEA) software and can aid in the design of knitting patterns for desired mechanical properties.

Summary: The study found that the prediction accuracy of the Hill48 yield model depends mainly on whether the material's anisotropic behavior follows a specific variation law, rather than being directly associated with the value of r. A method for identifying anisotropic parameters based on the conditional extremum of the cost function was proposed, which significantly improves the prediction accuracy for low-carbon steel materials.

Summary: A finite strain visco-elastic visco-plastic (three-dimensional) constitutive model is proposed in this study to predict the nonlinear behavior of amorphous polymers. The model modifies a well-known nucleation law and couples it with a nucleation criterion to suppress nucleation under compression and shear loadings. The growth of nucleated and initial voids is controlled by a modified Gurson's potential. The model is validated against literature results for polycarbonate and rubber-filled polycarbonate blends.

Summary: This paper proposes a visco-hyperelastic model to characterize the complex nonlinear and time-dependent properties of the small intestine. The model development consists of two steps: using a generalized anisotropic structure-based model to describe the hyperelastic behavior and employing the Prony series for the viscoelastic behavior. The developed model demonstrates superior accuracy compared to existing models, as confirmed by tension tests and relaxation tests on rabbit small intestine.

Summary: This article proposes an improved hyperelastic constitutive model based on the Yeoh model to enhance its prediction performance for multiaxial deformation of hyperelastic polymeric materials. The modified model includes an additional correction term, derived from residual strain energy, to accurately predict equibiaxial deformation. The proposed parameter identification method ensures accurate parameter estimation for the modified model. Experimental validation shows that the modified model has significantly improved predictive ability and wider applicability compared to existing models.

Summary: An alternative modelling framework is proposed to capture the rate-dependency in the deformation behaviour of isotropic elastomers. Instead of assuming an additive contribution to the elastic response, the framework considers the evolving model parameters of the basic hyperelastic function as functions of rate. The model shows favorable capturing results and suggests its potential for modeling the mechanical behavior of rubber-like materials under different loading conditions.

Summary: Fabric reinforced rubber composites are widely used in various fields due to their high strength and modulus. However, characterizing their anisotropy, hysteresis, and viscoelasticity remains challenging. In this study, a new anisotropic hyper-visco-pseudo-elastic model is developed by considering the Mullins effect, meso-damage of the fiber-matrix interface, and rate dependence. The model is validated through experimental and theoretical comparisons, demonstrating its potential for practical applications.

Summary: The conductive polymer hydrogel achieved transparent and highly ionically conductive properties through the organic combination of tannic acid-coated hydroxyapatite nanowires (TA@HAP NWs), polyvinyl alcohol (PVA) chains, ethylene glycol (EG), and metal ions. It integrates sensing, UV-filtering, water-retaining, and anti-freezing performances, and provides new ideas for the design of novel ionic skin devices. The inclusion of nanowires improves mechanical properties and UV-shielding ability, while the water-locking effect between EG and water molecules allows the hydrogel to exhibit freezing resistance and moisture retention.

Summary: The study found that using two fillers at the interface of glass fiber-aluminum laminates can simultaneously improve the Mode-I and Mode-II fracture toughness of the laminates. Due to the better dispersion of nano-aramid fibers in the epoxy matrix, their toughening performance is better than that of short-aramid fibers in this case.
