Summary: In this study, the sinusoidal four-variable shear deformation shell theory is for the first time used to investigate the size-dependent electro-hygrothermal bending of functionally graded sandwich piezoelectric cylindrical shells with a porous core. The model assumes that the shell is resting on two-parameter elastic foundations and subjected to elevated temperature, moisture concentration, external electric voltage, and transverse mechanical loads. The modified couple stress theory is employed to account for the size effect. An analytical solution for the governing equations is presented to obtain the displacements and stresses. The effects of geometric parameters, material length scale parameter, temperature rise, moisture concentration, electric voltage, porosity factor, core thickness, and foundation coefficients on the bending behavior are discussed.

Summary: This paper investigates the nonlinear thermo-electro-mechanical response of long sandwich cylindrical shells with functionally graded porous core and thin piezoelectric actuator layers. The equilibrium equations of the shell are established with the aid of the virtual displacement principle and von Karman kinematic assumptions. Analytical closed-form solutions are determined for a sandwich shell having simply-supported and clamped-clamped edge conditions. The results show that the nonlinear response of the sandwich shell is highly dependent on various factors.

Summary: An accurate nonlinear HTEE buckling analysis of piezoelectric fiber-reinforced composite cylindrical shells subjected to the coupled loading effects of axial compression and hydrostatic pressure was established, considering the nonuniform prebuckling effect.

Accurate critical buckling stresses, pressures, and explicit buckling modes for both axisymmetric and nonaxisymmetric buckling were obtained through the Galerkin method. A comprehensive parametric study of geometric parameters, end conditions, distribution patterns, and hygrothermal-electric multiphysical fields on the buckling behavior of HTEE composite cylindrical shells was also conducted and discussed.

Summary: This study aimed to extend the finite element method to cope with elastic-plastic problems by introducing the s-version FEM. The s-version FEM, which overlays a set of local mesh with fine element size on the conventional FE mesh, simplifies domain discretisation and provides accurate numerical predictions. Previous applications of the s-version FEM were limited to elastic problems, lacking instructions for stress update in plasticity. This study presents detailed instructions and formulations for addressing plasticity problems with the s-version FEM and analyzes a stress concentration problem with linear/nonlinear material properties.

Summary: This paper investigates the imbalance problem in rotating machinery and finds that mass imbalance can induce lateral-torsional coupling vibration. By developing a model and conducting detailed analysis, it is discovered that mass imbalance leads to nonlinear time-varying characteristics and there is no steady-state torsional vibration in small unbalanced rotors. Under largely unbalanced conditions, both resonant and unstable behavior can be observed, and increasing lateral damping can suppress instability and reduce lateral amplitude in the resonance region.
