Piezoelectric beams are widely used in micro-electromechanical systems. At the microscale, influence of size effect on a piezoelectric beam cannot be ignored. In this paper, higher-order elasticity theories considered to predict behaviors micro-structures and size-dependent dynamic model laminated microbeam is established. The governing equations for derived using variational principle. natural...

A cellular imaging system, optimized for unstained cells seeded onto a thin substrate, is under development. This system will be a component of the endstation for the microbeam cell-irradiation facility at the University of Surrey. Previous irradiation experiments at the Gray Cancer Institute (GCI) have used Mylar film to support the cells [Folkard, M., Prise, K., Schettino, G., Shao, C., Gilch...

In addition to its metal-insulator transition (MIT), VO2 exhibits a rich phase behavior of insulating monoclinic (M1,M2) and triclinic (T) phases. By using micro-Raman spectroscopy and independent control of temperature and uniaxial strain in individual single-crystal microbeams, we map these insulating phases with their associated structural changes as represented by their respective phonon fr...

In this paper, a microstructure-dependent magneto-electro-elastic functionally graded porous (MEEFGP) beam model is proposed using variational approach. To account for the microstructure effect, extended modified couple stress theory incorporated in new model. addition, porosity variation of two-phase through thickness direction also considered. The developed verified terms its correctness with...
