The estimation of various methods of determining of strong characteristics of glass samples is carried out. The method of the research of glass samples with the orientation of the widerside of the cross-section of the sample, in contrastto the different research methods based on thevertical orientation of the wider side of the crosssection of the sample. The main physical and mechanical characteristics of ordinary sheet glass when tested for bending, and the bending strength itself is determined. Statistical analysis of theobtained results was performed using the twoparametric Weibull distribution.The object of the study was to determine the strength characteristics, which by standard methods complicates the process of making standard samples and leads to a large welcome material. For the research, the optimal technologies of manufacturing and consumption of materials of research samples were developed.The method of studying the strength of glass at three-point bends was used, and to determine the modulus of elasticity used methods to determine its relative deformations using strain gauges and deflections. The statistical method for estimating strength was the two parametric Weibulldistribution.The result confirms the feasibility of using the recommended approach for the manufacture and testing of test specimens to determine their strength, which is an additional reduction in costs as a material. The use of the Weibull statisticaldistribution allowed the characteristic values of strength that developed for individual series of samples with sufficient accuracy.The study confirmed the feasibility of further research on the stability of flat glass elements and the use of accurate methods for determining the modulus of elasticity of glass. The result of the evaluation of the influence of the orientation of the samples on the experimental stand and the influence of the flat form of deformation of the value of strength and modulus of elasticity in vertically oriented samples is obtained. |
