The main purpose of the present article is to present a forced vibrational analysis for a new intelligent sandwich plate made up of various layers. The proposed intelligent structure contains a porous metal foam core, super stiff double-FG nanocomposite layers, and piezomagnetic actuators which will be actuated magnetically and electrically. For the metal foam core of the structure, three kinds of porosity patterns are considered and, in the double-FG nanocomposite layers, Carbon Nanotubes (CNTS) are dispersed through various FG patterns in an FG metal-ceramic matrix. The power-law function is used to form the FG metal-ceramic matrix of the nanocomposite layers. Then, first-order shear deformation theory (FSDT) is utilized to derive the governing equations, and the resonance and natural frequencies of the proposed sandwich structure with simply-supported boundary conditions are obtained employing Navier’s analytical solution method. Finally, the effects of various parameters such as the CNTs’ volume fraction, magnetic and electric potentials, porosity patterns, core-to-nanocomposite layers thickness ratio, power-law index, etc. on the resonance behavior of the structure will be discussed based on tabular and graphical results. The results demonstrate that the occurrence of the resonance phenomenon in such a multi-layered structure remarkably depends on the mentioned parameters and can be somehow controlled by applying magnetic and electric potentials to the piezomagnetic actuators connected to the top and bottom of the structure.

Materials that can recover the function of lost or damaged parts, called self‐healing materials, have attracted attention due to their wide usage in different fields such as water refinery, coatings, robotics, and especially, biomedical applications. Depending on whether the self‐healing component is added to the polymer or is inherent to the polymeric matrix, the self‐healing properties of the polymeric materials can be classified into extrinsic and intrinsic self‐healing. Hydrogels are one of the most used polymers in self‐healing applications for various purposes, including tissue engineering, drug delivery, etc. Nanoparticles can endow some essential features to hydrogels, such as improving mechanical properties, more efficient healing ability, conductivity, and antibacterial and magnetic features. In the current study, various biomedical applications of self‐healing polymers using nanoparticles are discussed in detail, showing the impact of addition of nanoparticles. Perfect antibacterial properties with the addition of copper sulfide or silver nanoparticles were achieved. In addition, enhancing compression modulus up to three times and endowing conductivity to the hydrogel as the effect of carbon nanotube addition and better mechanical properties caused by graphene oxide and iron oxide nanoparticles were reported. These are just a few examples of the results achieved by adding nanoparticles to the self‐healing polymers described in this study.
