FIELD: glass industry.
SUBSTANCE: group of inventions relates to a terminal, glazing, use of a terminal in a non-destructive method of confirming that a glazing installed in a structure withstands a dynamic impact effect, and the finite element method evaluation system, that the glazing installed in the structure withstands the dynamic impact action. Terminal is designed to calculate maximum stresses on each glass sheet of glazing and is used in a non-destructive method of confirming that glazing 1 installed in structure 7 withstands a dynamic impact effect and/or in a method of making glazing 1. Glazing 1 installed in structure 7, must withstand dynamic impact action, such as poultry impact in case of its installation in aircraft. Glazing 1 comprises at least one glass sheet, and method of determination includes stages, at which by numerical finite element model of glazing installed in structure and subjected to impact action, using the law of behavior of the material of each glass sheet, calculating the envelope of maximum stresses for each glass sheet of glazing; for each glass sheet of glazing, envelope of maximum stresses is compared with breaking stress of glass sheet, obtained by an experimental method for determining the breaking stress of a glass sheet, selected depending on the type of impact.
EFFECT: enabling determination of the rigidity of the glazing material and the fastening system.
