Vibration and buckling characteristics of functionally graded nanoplates subjected to thermal loading based on surface elasticity theory
TL;DR: In this paper, the buckling and vibration responses of nanoplates made of functionally graded materials (FGMs) subjected to thermal loading are studied in prebuckling domain with considering the effect of surface stress.

Size-Dependent Resonant Frequency and Flexural Sensitivity of Atomic Force Microscope Microcantilevers Based on the Modified Strain Gradient Theory
TL;DR: In this article, a modified strain gradient elasticity theory is applied to the classical Euler-Bernoulli beam theory to develop a non-classical beam model which has the capability to capture size-dependent behavior of microcantilevers.

Vibration of Piezoelectric Nanowires Including Surface Effects
TL;DR: In this article, surface and piezoelectric effects on the vibration behavior of nanowires were investigated by using a Timoshenko beam model, and the electric field equations and the governing equations of motion were derived with the consideration of surface effects.

Determination of dynamic material properties using laser measurement technique in split Hopkinson pressure bar
TL;DR: In this article , a laser measuring system is designed, implemented, and calibrated in order to obtain the dynamic properties of different materials using split Hopkinson pressure bar test, which is a non-contact one, the displacements of bar/sample interfaces are measured directly using a laser extensometer technique, in addition to the strain, the tested sample can be calculated.
