The article is devoted to the thermal calculation of a flat plate solar collector. In this case, boundary conditions are third kind. solution found in transition an elliptical coordinate system. author has obtained analytical for distribution temperature field collector with cross-section at zero ambient partial adiabatic isolation form functional series using hypergeometric functions.

The transient response of a flat circular plate to a sudden impact has been studied experimentally and theoretically. High-speed electronic speckle pattern interferometry reveals the presence of pulses that travel around the edge of the plate ahead of the bending motion initiated by the strike. It is found that the transient motion of the plate is well described by Kirchhoff thin-plate theory o...

Abstract—Punching shear failure is usually the governing failure mode of flat plate structures. Punching failure is brittle in nature which induces more vulnerability to this type of structure. In the present study, a 3D finite element model of a flat plate with low reinforcement ratio and without any transverse reinforcement has been developed. Punching shear stress and the deflection data wer...
