Thermomechanical vibration of biocompatible sandwich plates with graphene-reinforced foam core under mechanical and thermal loads

This study models and analyzes the thermomechanical vibration behavior of biocompatible sandwich plates under compressive forces, thermal fields, and magnetic fields, employing high-order plate theory. The sandwich plate is composed of a solid and foam structured ZK60 magnesium alloy reinforced with graphene in the core layer, with surface layers consisting of functionally graded ZK60 ceramic material in the inner sections and zirconia ceramic material in the outer sections. The results indicate that the metal foam structure in the core layer and the distribution of metal ceramic materials in the surface layers significantly influence the thermomechanical vibration behavior of the sandwich plate. The application of an external magnetic field was found to enhance the thermal buckling resistance of the sandwich plate. The study results indicate that the wave propagation characteristics of the sandwich plate can be significantly influenced by different foam structures in the core and top layers, as well as by variations in material distribution qualities. The study’s findings are expected to substantially enhance the existing body of research and are applicable to emerging applications in fields such as sonar radars, aircraft, and marine vehicle stealth technologies.
