Stress Analysis of FGM Cylindrical Shell
This paper addresses the analysis and solution of a simply supported functionally graded material (FGM) infinite cylindrical shell under a transverse sinusoidal load, employing a semi-analytical method. The cylindrical shell's constituent materials exhibit varying properties according to an exponential law across its thickness, posing a complex structural challenge. Utilizing equilibrium equations in plane polar coordinates, we reduce the system of stress equilibrium equations to coupled first-order ordinary differential equations in terms of stress and displacement variables. The semi-analytical approach transforms the problem into a two-point boundary value problem into initial value problem by a fourth-order Runge–Kutta Gill method for numerical integration. We investigate the influence of gradation factor and aspect ratio on the flexural behavior of the FGM cylindrical shell, providing insights into structural responses. Validation of our solution against existing literature ensures the accuracy of our approach. These numerical results contribute to understanding FGM cylindrical shell behavior and serve as a benchmark for validating approximate theories, offering a valuable tool for researchers and engineers in the design and optimization of structures involving functionally graded materials.
