The problem of several finite moving cracks in a functionally graded material is solved by dislocation technique under the condition of anti-plane deformation. By using the Fourier transform the stress fields are obtained for a functionally graded strip containing a screw dislocation. The stress components reveal the familiar Cauchy singularity at the location of dislocation. The solution is em...

The area of micro strip antennas has seen some inventive work in recent years and is currently one of the most dynamic fields of antenna theory. An overview of work done in the area of micro strip antennas is presented and several recent developments in the field are highlighted. In addition, new antenna configurations that improve electrical performance and manufacturability are described. Thi...

The aim of this study was to assess the effects of strip cropping and different weed control methods on the yield and yield structure of dent maize, narrow-leafed lupin and spring oat. A split-plot design with four replications was conducted in 2008-2010. The following factors were analysed in the experiment: I. Cultivation method – sole cropping and strip cropping; II. Weed control method ...

ABSTRACT In this study, the vibration and sound radiation from the double-layered strip plate with air cavity between the upper and lower plates are investigated by using the waveguide finite and boundary element method. The interaction between the structural and acoustic waves propagating along the double-layered strip plate is investigated by observing the dispersion relations of the waves. T...

To determine the exact distribution of tensile stress in a cold rolled strip, evolution caused by lateral uneven velocity outside deformation zone strip is examined. The finite difference method employed to solve problem. Different factors, including width and form amplitude initial on evolution, are analyzed. On one hand, improve calculation speed, “Gaussian” curve proposed fit results calcula...
