Size dependent large displacements of microbeams and microframes

چکیده
The size dependent large displacement behavior of planar microbeams and microframes is studied in this paper using a corotational beam element. To account for the effect, modified couple stress theory (MCST) employed conjunction with Euler-Bernoulli deriving internal force vector tangent stiffness matrix Newton-Raphson based iterative procedure used combination arc-length method to solve nonlinear equilibrium equation trace paths. Various are analyzed show influence effect on deflection microstructure. obtained result reveals that plays an important role response, displacements structure over estimated by ignoring effect. A parametric study carried out highlight material length scale parameter microframes.

Size-Dependent Large Amplitude Vibration Analysis of Nanoshells Using the Gurtin-Murdoch Model
Shell-type nanostructures have recently attracted a lot of attention due to their several applications. The surface stress effect plays an important role in the mechanical behavior of such structures because of their large surface-to-volume ratio. In this paper, an analytical approach is presented for analyzing the geometrically nonlinear free vibrations of cylindrical nanoshells. In order ...
متن کاملEstimation of optical flow for large displacements
In this paper we present a new method to estimate optical flow for large displacements. It is based on prediction of global flow field parameters, performs better than multiresolution estimation methods and has been verified using standard test sequences as well as real-world data. Global flow field parameters can be estimated from optical flow measurements in all flow regions. They can then be...

متن کاملModeling capillary forces for large displacements
Originally applied to the accurate, passive positioning of submillimetric devices, recent works proved capillary self-alignment as effective also for larger components and relatively large initial offsets. In this paper, we describe an analytic quasi-static model of 1D capillary restoring forces that generalizes existing geometrical models and extends the validity to large displacements from eq...
