چکیده

Recent advances in the development of new engineering materials have led to the creation of different types of porous materials. These materials can be used to remove harmful compounds from soil, air, and water as a method of environmental remediation. This paper aims to study the mechanical behavior of Functionally Graded (FG) porous materials. In terms of engineering applications, these weight-efficient materials may allow for an improvement in the structural performance of certain mechanical systems. In this analysis, the effects of porosity distribution in curved thick panels made of FG porous materials are numerically investigated using the Differential Quadrature Method (DQM). Two types of porous materials, including both open-cell and saturated closed-cell panels with three symmetric, non-symmetric, and uniform porosity distributions, are considered. Elasticity theory is used to develop the governing differential equations of the curved panel. The physical behavior of a curved panel and the influences of porosity distribution, boundary conditions, and geometrical characteristics (i.e., angle, length, radius, and thickness) of the panel are investigated.
