Abstract
This study investigates the static buckling behavior of functionally graded porous (FGP) plates. A theoretical model is developed based on the first-order shear deformation theory (FSDT), while the Ritz method is utilized to solve the governing equations. In this model, the material properties are considered to vary continuously through according to three distinct porosity schemes, including uniform, symmetric, and asymmetric distributions. The validity and accuracy of the developed model are confirmed by benchmarking the results against available data reported in the literature. A comprehensive numerical study is carried out to explore the effects of key parameters, such as porosity characteristics (distribution patterns and coefficients) and geometric properties, on the critical buckling load. The outcomes of this investigation contribute to a better understanding and serve as a valuable resource for the design and optimization of engineering structures fabricated from advanced functional materials.
Background/Aim: This study develops and verifies a finite-difference formulation for the linear buckling analysis of rectangular power-law functionally graded material (P-FGM) plates, based on first-order shear deformation theory (FSDT). The aim is to provide an accurate, computationally efficient numerical approach fo...

This study presents a modified variational modeling method for the flexural–torsional buckling of functionally graded porous (FGP) curved beams. Unlike conventional methods that rely on strictly admissible functions, the proposed framework accommodates arbitrary orthogonal polynomial basis functions and segment-wise...

The free vibration analysis of a bidirectional functionally graded (2D-FG) curved structure with a through-thickness longitudinal central crack is performed in the current analysis. The model employs higher-order displacement theory for kinematics, taking into consideration both situations with even and uneven porosi...

This study aims to numerically investigate the mode I, II, and III fracture behaviors of additively manufactured degradable, bioplastic polylactic acid (PLA) lattice specimens. Numerical simulations were performed using the eXtended Finite Element Method (XFEM) based on the extracted PLA's mechanical and fracture mat...

This study presents an analytical formulation based on the inverse hyperbolic shear deformation theory (IHSDT), a non-polynomial higher-order shear deformation theory, for the static, buckling, and free vibration analyses of functionally graded graphene nanoplatelets reinforced composite (FG-GNPRC) plates. The IHSDT sa...
