TL;DR: In this paper, the nonlinear free vibration of microbeams made of functionally graded materials (FGMs) is investigated based on the modified couple stress theory and von Karman geometric nonlinearity.

TL;DR: In this paper, the dynamic stability of microbeams made of functionally graded materials (FGMs) is investigated based on the modified couple stress theory and Timoshenko beam theory, and the boundary points on the unstable regions are determined by Bolotin's method.

TL;DR: In this article, the nonlinear vibration of the piezoelectric nanobeams based on the nonlocal theory and Timoshenko beam theory was investigated, and a detailed parametric study was conducted to study the influences of the non-local parameter, temperature change and external electric voltage on the size-dependent non-linear vibration characteristics of the PNE.

TL;DR: In this article, a survey of tunable and active phononic crystals and metamaterials is presented, including bandgap and bandgap engineering, anomalous behaviors of wave propagation, as well as tunable manipulation of waves based on different regulation mechanisms: tunable mechanical reconfiguration and materials with multifield coupling.

TL;DR: In this paper, a modified couple stress model was developed for free vibration analysis of microplates. But the model is not suitable for the analysis of large-scale microstructures and it cannot describe the size effect that the classical Mindlin model is unable to describe.
