International Journal of Mechanical System Dynamics, Volume 5, Issue 3, Page 535-563, September 2025.ABSTRACT This article investigates the nonlinear vibration behavior of porous multidirectional piezoelectric functionally graded nonuniform (PFGN) plates resting on orthotropic variable elastic foundations and subjected to hygrothermal loading. The sigmoidal law is employed to define the multidirectional gradation properties, incorporating porosity ...

Analysis of the mechanical behavior of functional gradient porous plates on an elastic foundation
Scientific AfricanSummary: This study presents an in-depth analysis of the bending behavior of porous functionally graded material (P-FGM) plates resting on a Winkler–Pasternak elastic foundation. Two types of transverse loading are considered: uniform and sinusoidal. The

Beam Elements on Linear Variable Two-Parameter Elastic Foundation [PDF]
Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2008 The traditional way to overcome the shortcomings of the Winkler foundation model is to incorporate spring coupling by assemblages of mechanical elements such as springs, flexural elements (beams in one-dimension, 1-D, plates in 2-D), shear-only layers ...
