Summary: A beam finite element model is proposed for static and free vibration analyses of FGM sandwich beams with viscoelastic nonlinear material behavior. Different viscoelastic frequency-dependent laws, Timoshenko 1st order, and Reddy's higher order shear models are used. The stiffness matrix is nonlinear and frequency dependent. The study shows that beam behavior is sensitive to the loss factor, and damping properties are nonlinearly dependent on the power law index. Boundary conditions affect vibration modes.

Summary: In this study, bending and free vibration analyses are conducted on sandwich FGM beams using the recently proposed HOZT. Different material gradation laws and stress distributions across the thickness are examined, revealing the distinct behavior of unsymmetric beams compared to symmetric ones. The findings provide valuable insights for future studies in this field.

Summary: This work introduces two layerwise electro-elastic user-elements for static and free vibration analysis of piezoelectric composite plates, with predictive capabilities assessed through comparison with three-dimensional exact solutions. The results demonstrate an advantage of the electric potential quadratic z-expansion for static analysis, while showing negligible improvements on the evaluation of the first 12 natural frequencies.

Summary: In this study, the free vibration of porous FGM sandwich plates in a thermal environment is analyzed. Finite element modeling and surrogate modeling are used to investigate the influence of uncertain material properties on the vibration frequency. Parametric studies and sensitivity analysis reveal that the mass density is the most sensitive parameter affecting the vibration frequency of FGM sandwich plates.

Summary: A new quadrilateral element Q4 gamma(s) is developed in this paper, which has 5 DOFs per node and is shear-locking free, using a discrete shear projection method (DSPM). This element formulates independent transverse shear strains and applies discrete shear strains along each element side to obtain constant shear strains. The element shows good convergence behavior, high reliability, and accuracy in static and free vibration analysis of functionally graded material plates.

Summary: Closed-form unified solutions for static short/open-circuit sensing and voltage/charge actuation of moderately thick beam cantilevers with co-localized surface-bonded piezoelectric patches are presented for the first time using the distributed transfer functions (DTFs) method. The smart beam is divided into three segments, with elastic clamp and free sides and an elastic core sandwiched between two piezoelectric patches. The solutions were validated against existing literature benchmarks and showed very good correlations with analytical and finite element results.

Summary: This study presents the static and free vibration analysis of doubly-curved functionally graded material shells using various equivalent single-layer shell theories considering shear deformation and rotary inertia effects. The generalized shell theory used in this study unifies different equivalent single-layer shell theories by making the displacement field independent of the transverse shear strain function. Equations of motion are derived using Hamilton's principle and solved analytically using Navier's technique, providing new numerical results for future researchers.

Summary: This study investigates the static and free vibration behaviors of 2D FGM beams with variable constituents over the cross section using a finite element approach, considering axial, bending, and shear couplings. It compares different models and explores the effects of boundary conditions, slenderness ratio, and FGM power law parameter on the behavior of FGM beams in static and dynamic analyses. The presence of short beams and shear effects are found to be important factors affecting the behavior of FGM beams.

Summary: This article investigates the influence of porosity and localized edge loads on the vibration and buckling characteristics of functionally graded material (FGM) plates using the finite element (FE) method. The results show that the vibration and buckling responses are affected by different types of localized edge loads on plates with varying porosity distributions. Parametric studies are conducted to analyze the effects of various parameters on the buckling load and natural frequency of porous FGM plates.

Summary: This article examines the free vibration response of functionally graded cylindrical and spherical porous shells with temperature-dependent material properties. The effective material properties are determined using the rule of mixture with porosity phases. The equation of motion is derived based on a curved 8-node degenerated shell element formulation. The study focuses on two different material mixtures and investigates the influence of material constituents, power-law indexes, boundary conditions, radius to thickness ratio, porosity parameter, and temperature gradient on the natural frequencies.
