The effect of fibre orientation on buckling behaviour in a rectangular composite laminate with central circular hole under uniform in-plane loading has been studied by using finite element method. The critical buckling loads with different fibre orientation in an orthotropic composite laminate (E-glass/epoxy) were obtained. The deformation behaviour of the plate is shown for modes, i=1,2. Studi...

A laboratory-based experiment procedure of reception plate method for structure-borne sound source characterisation is reported in this paper. The method uses the assumption that the input power from the source installed on the plate is equal to the power dissipated by the plate. In this experiment, rectangular plates having high and low mobility relative to that of the source were used as the ...

[1] The shear tractions that mantle flow exerts on the base of Earth’s lithosphere contribute to plate-driving forces and lithospheric stresses. We investigate the sensitivity of these tractions to sub-lithospheric viscosity variations by comparing shear tractions computed from a mantle flow model featuring laterally-varying lithosphere and asthenosphere viscosity with those from a model with l...

Pressure measurements in industries, biomedical and marine environment are of utmost importance to better understand the process stability, ocean processes. The influence of in-plane stresses of silicon plate with square, rectangular and circular shape have been investigated. The area of square, rectangular and circular form of elastic element has been approximated to be equal and the thickness...

This paper presented development work of an in situ method for damage detection in thin-wall structures using embedded two-dimensional ultrasonic phased arrays. Piezoelectric wafer active sensors were used to generate and receive guided Lamb waves propagating in the plate-like structure. The development of a generic beamforming algorithm that does not require parallel ray assumption through usi...

Electrophoretic deposition of carbon nanotubes (CNTs) using alternating current electric fields (0.01-1000 Hz) is reported. Pure acetone was used as suspending medium. Two parallel gold electrodes were used as depositing substrate. The effect of depositing parameters such as frequency and three waveforms (sinusoidal, rectangular and triangular) on deposit yield was investigated. According to ou...
