Abstract
The main methods of testing the strength of glass are considered and the results of measuring the strength of glass according to the proposed experimental methods are presented. A step-by-step guide for analyzing strength data using a two-parameter Weibull distribution is also described. The modulus of elasticity was determined, which was calculated by two methods. The first method was to analyze the data of strain gauge readings, and was calculated according to Hooke's law. The second method was to calculate the modulus of elasticity by the formula derived from the equation for calculating the deflection. This paper considers three series of prototypes, each of which consists of ten experiments. Experimental samples of series I are made of ordinary sheet glass. Series II is made of heat-strengthened sheet glass, and prototypes of series III were made of tempered sheet glass. A comprehensive review of existing test methods for the strength of glass. The features of the used bending tests and statistical analysis of the measured strength data are described. The results may be of particular interest to specialists in modern design of load-bearing structures made of glass.
