In the paper "Thermal buckling of P-FGM sandwich beam with porous core on elastic foundation", a coupled effect of thermal and electrical loadings on the thermal buckling behavior of functionally graded material (FGM) sandwich beam resting on Pasternak foundation is investigated. The symmetric multi-layered beam consists of a foam core, two middle FGM layers, and two outer piezoelectric layers. It is assumed that the beam is subjected to a constant voltage and a uniform/linear temperature rise.

In this work, the free vibration analysis of Timoshenko microbeams made of the Functionally Graded Material (FGM) on the Winkler–Paternak elastic foundation based on the Modified Coupled Stress Theory (MCST) is investigated. Material characteristics of the beam vary throughout the thickness according to the power distribution and are estimated though Mori–Tanaka, Hashin–Shtrikman and Voigt homogenization techniques.

Vibration analysis of multi-span bidirectional functionally graded material (2D-FGM) beams subjected to a moving load is presented by using a high-order deformation theory. The material properties of the beam are assumed to vary continuously in the thickness and longitudinal directions by a power-law distribution. The dynamic response of the beam is computed with the aid of the Newmark method.

In this paper, the mechanical behavior of symmetric FGM sandwich beams where each component layer is made from different funtionally graded materials and conected to one another by shear connectors is carried out. The finite element formulations are constructed based on the first-order shear deformation theory (FSDT) of Timoshenko for beam and finite element method. The calculation program is coded in the MATLAB environment and compared the results with particular cases.

In this paper, a two-dimensional functionally graded sandwich (2D-FGSW) beam model formed from three constituent materials is proposed and its free vibration analysis is carried out for the first time. The beam consists of three layers, a homogeneous core and two skin layers of 2D-FGM. The material properties of the skin layers are considered to vary in both the thickness and longitudinal directions by power gradation laws.

In the present work, the large displacement behaviour of FGSW beams in thermal environment is studied by a finite element formulation. The beams considered herein consist of three layers, a homogeneous core and two FGM skin layers. The material properties are assumed to be temperature dependent, and they are graded in the thickness direction by a power gradation law. Based on Antman beam model, a nonlinear beam element using linear interpolation is formulated in the context of the total Lagrange formulation.

This paper presents crack identification in multiple cracked beams made of functionally graded material (FGM) by using stationary wavelet transform (SWT) of mode shapes and taking into account influence of Gaussian noise. Mode shapes are obtained from multiple cracked FGM beam element and spring model of cracks. The theoretical development was illustrated and validated by numerical examples. The investigated results show that crack identification method by using SWT of mode shapes is efficient and realizable.

In this paper, free vibration of bidirectional functionally graded sandwich (BFGSW) beams is studied by using a finite element formulation. The beams made from three distinct materials are composed of three layers, a homogeneous core and two bidirectional FGM face layers with material properties varying in both the thickness and longitudinal directions by power gradation laws. Based on the first-order shear deformation theory, a finite element formulation is derived and employed to compute the vibration characteristics of the beams with various boundary conditions.

In this paper, a higher-order Timoshenko beam element is developed and employed in studying free vibration of 2-D FGM Timoshenko beams. The material properties of the beams are considered to vary in both the thickness and longitudinal directions by a power-law distribution. Based on Timoshenko beam theory, equations of motion are derived from Hamilton’s principle and they are solved by a finite element procedure based on the developed beam element.

This thesis aims to develop finite element models for studying vibration of FGM porous beams in thermal environment under moving loads. Both analytical method and finite element analysis are employed in the thesis. The analytical method is used to derive equations of motion for the beam, and the finite element method is then employed to solve the governing equations and to determine the dynamic characteristics of the beams.
