Static and Dynamic Deflection Characteristics of Cracked Porous FG Panels

Abstract

The deflection responses of the cracked porous graded structure under the variable loading conditions (static and dynamic) are investigated numerically with the help of a commercial tool (ABAQUS). The model includes the grading in two different directions (along the thickness and length by setting the relevant volume fraction exponents [Formula: see text] and [Formula: see text], i.e., of the functionally graded material (FGM) for the analysis purpose. Additionally, different material gradings, i.e., power-law (P-FGM), sigmoid (S-FGM), and exponential (E-FGM), are adopted to achieve the distribution patterns within the FG panel. Further, the porosity and the damage (crack) have been introduced in the graded structural panel. The python scripting language is used to model the FGM plate via the batch input technique, i.e., ABAQUS kernel, instead of the standard GUI interface. The accuracy has been confirmed by validating the results with the published available results, and the applicability is stated through a series of numerical examples by changing input parameters.
