Special Issue Information

Dear Colleagues,

Advanced materials such as lightweight and high-strength fiber-reinforced laminates, sandwich materials, nanocomposites, and functional gradient materials are widely used in aerospace, marine, automobile, rail, weapons, and other industries. Currently, there are a large number of advanced materials that are in service in various thermal environments, such as composite panels in high-speed aircraft, high-temperature turbine blades in aero-engines, and composite wings in unmanned solar aircraft. Due to the effect of high temperatures, which may reach hundreds or thousands of degrees Celsius, after a period of servicing time, these composite materials and structures will undergo severe vibration, weakened stiffness and strength, and dynamic fatigue problems, thus causing a possible catastrophic accident for the whole working components and systems. Unfortunately, experimental and theoretical reports on vibration and thermodynamic studies of advanced materials are still insufficient. Therefore, these areas will continue to be hot topics in advanced materials research for a long time to come.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

An optimization design of the bending-vibration resistance of magnetorheological elastomer carbon fibre reinforced polymer sandwich sheets (MECFRPSSs) was studied in this paper. Initially, by adopting the classical laminate theory, the Reddy’s high-order shear deformation theory, the Rayleigh-Ritz method, etc., an analytical model of the MECFRPSSs was established to predict both bending and vibration parameters, with the three-point bending forces and a pulse load being considered separately. After the validation of the model was completed, the optimization design work of the MECFRPSSs was conducted based on an optimization model developed, in which the thickness, modulus, and density ratios of magnetorheological elastomer core to carbon fibre reinforced polymer were taken as design variables, and static bending stiffness, the averaged damping, and dynamic stiffness parameters were chosen as objective functions. Subsequently, an artificial bee colony algorithm was adopted to execute single-objective, dual-objective, and multi-objective optimizations to obtain the optimal design parameters of such structures, with the convergence effectiveness being examined in a validation example. It was found that it was hard to improve the bending, damping, and dynamic stiffness behaviours of the structure simultaneously as the values of design variables increased. Some compromised results of design parameters need to be determined, which are based on Pareto-optimal solutions. In further engineering application of the MECFRPSSs, it is suggested to use the corresponding design parameters related to a turning point to better exert their bending-vibration resistance.
