Springback of laterally loaded circular plates
Springback is a common phenomenon in sheet metal forming, caused by the elastic redistribution of the internal stresses during unloading.
Circularly polarized meshed patch antenna
A circularly polarized meshed patch antenna design is presented. The proposed antenna consists of two square meshed patches, which generate two orthogonal linear polarizations at two slightly different frequencies. A common proximity feedline...
A Numerical Study on Flow Characteristics of 2D Vertical Liquid Jet Striking a Horizontal Surface
We studied numerically impingement of vertical liquid jets of moderate Reynolds number for both Newtonian and non-Newtonian liquids to clarify the structure formation of circular hydraulic jump and the phenomenon of jet buckling. First, we have...
Stress Analysis of Composite Plates with Non-circular Cutout
The high stress concentration at the edge of a non-circular shaped cutout is of practical importance in designing of the engineering structures. These types of cutout usually are evaluated either experimentally or numerically. In this paper...
Effects of Frequency Variation at Inlet Flow on the Vortex Shedding Frequency Behind a Circular Cylinder
In many applications,
Experimental Investigation of a Compact Dual-Band Circular Polarization Microstrip Antenna
In this paper, a compact, easy to fabricate single-feed multiple slotted square patch antenna is proposed to obtain dual-band Circular Polarization (CP) radiation patterns. To obtain dual operation, four T-shaped slits are inserted at the patch...
HSA-interaction studies of some novel uranyl complexes of isothiosemicarbazone
UV-Vis, fluorescence and circular-dichroism spectroscopies. The results show that the complexes quench the fluorescence peak of HSA in static way. According to calculated thermodynamic parameters, hydrophobic interactions are the main forces...
Comparison between the circular and square collar in reduction of local scouring around bridge piers
In this study operation of two types of circular and square collars has been investigated on a single cylindrical pier. The results showed that using of these two types of collars cause to reduction of scour depth especially under...
An investigation into the influence of deformables dies on springback of circular plates
The technique of sheet stamping by deformable forming tools (SSDFT) has been recognized as a promising alternative to control the springback of sheet blanks................................
