Two-dimensional, averaged over the thickness of layer, mathematical theory spreading a plastic layer on plane has been studied. General and simplified formulations boundary value problem were presented. The stretching strip by forces applied its “clamped” ends was investigated. analysis various modes process carried out, which are determined both total compression force tensile force. Mathemati...
This paper aims to improve planar shape prediction accuracy in the rolling process of medium and thick plates. We present a model based on strip method that addresses limitations predicting variations at head tail ends rolled pieces. By analysing process, we introduce concept an imaginary longitudinal length difference represent characteristics effectively. change metal deformation zone, calcul...
This paper present a method to build up statically admissible slip-line field (the of characteristics) and, as result, the stresses compression three-layer symmetric strip consisting two different rigid perfectly plastic materials between rough, parallel, plates (for case: shear yield stress inner layer is greater than that outer layer). Under conditions sticking regime at bi-material interface...
transfer table is an essential stage between roughing and finishing rolling stands in a hot-strip rolling mill. high temperature and long time that strip is exposed to air at this stage cause a considerable heat loss that accounts for uneven temperature distribution, non-uniform surfaces, reduced product quality and increased production costs. using thermal shields on the transfer table is cons...
Two semi-infinite elastic plates are joined along a line forming a wedge structure with unilateral fluid loading in the outer sector of the two plates. The structure is modeled using thin plate theory, allowing freely propagating flexural and longitudinal waves. The junction is mechanically connected with an applied force and moment acting there to simulate a possible internal connection. The g...
A method of determination of a gamma quantum absorption point in a plastic scintillator block using a matrix of wavelength-shifting (WLS) strips is proposed. Application of this method for improvement of position resolution in newly proposed PET detectors based on plastic scintillators is presented. The method enables to reduce parallax errors in reconstruction of images which occurs in the pre...
