“…In this context, the 4th order R-K method, in particular, enjoys extensive utilization in addressing nonlinear dynamic issues pertaining to shells [8][9][10][11][12][13][14]. Its prevalence extends beyond shell dynamics, finding widespread application in resolving various nonlinear challenges across the scientific and engineering domains [15][16][17].…”

This study delves into nonlinear vibratory responses of functionally graded (FG) tubes subjected to transverse loads, considering material properties that vary with temperature. A refined beam model established for the tubes satisfies the stress boundary conditions on inner and outer surfaces of the tubes. The nonlinear vibration equations for these functionally graded tubes are meticulously derived with employment of the Zhang–Fu high-order shear deformation beam model, the von Kármán equation, and Hamilton’s principle. The proposed approach is applied to address externally excited nonlinear FG tube systems, encompassing both the 2 degrees of freedom (DOF) single-mode systems and 6 DOF multi-mode systems. Utilizing Galerkin’s method, the resulting discretized nonlinear governing equations allow for the analyses of single and multi-mode tubular system behavior. In solving for the tubular system, an approach implementing the P-T method is managed to be implemented, which yields a continuous semi-analytical solution throughout the entire time domain considered. The approach also demonstrates the advances on the development of a genuinely new computational method with broad impact. In comparison to the widely used Runge-Kutta (R-K) method, the proposed approach demonstrates superior efficiency, accuracy, and reliability, especially for highly nonlinear and complex systems like the FG tubular systems.

The primary factors of the widespread use of induction melting furnaces are uniform metal and heat distribution due to its mixing features, low alloy losses, excellent temperature and composition control, versatility in processing different materials, the ability to quickly start the process from a cold state when needed, and the absence of air pollution problems. In induction heating, not all sides of the part to be heated receive an equal amount of heat. Only if the part to be heated is of the type that conducts heat very well can all sides of the part be heated close to each other. Induction heating produces high heat on the surface, less on the inner parts, and least on the center of the material. This heating varies depending on the frequency of the current source and the penetration depth. In this study, a model was created in ANSYS numerical analysis program by taking the current, which is one of the electromagnetic and thermal parameters affecting the temperature distribution in the metalic material in induction heating, at different values. In the simulation model created, three-dimensional numerical analysis results of a cylindrical metallic material were obtained. In the simulation program, the power and frequency required for the design of the induction coil and the magnetic permeability, resistivity, heat transfer coefficient of the material and the position of the material in the inductor are determined as boundary conditions. Depending on these variables, the temperature and magnetic field distributions on the material were obtained. In addition to the numerical analysis, a cylindrical metallic material with known properties was placed in a specially manufactured induction coil and the temperature values on the material were measured to verify the numerical analysis. ANSYS modeling results with the same material dimensions, properties, and other parameters used in the experiment, were given and examined in comparison with the experimental results.
