The paper describes the results obtained from the tensile and compression experimental tests of the structural tempered glass plates with three different types of stress concentrators and without them. The types of stress concentrator have been chosen as close as possible to those usually found in practical situations and also taking into account the cases known from the literature. All tests are performed under the same conditions and with the step of loading 1.0 kN for tension and compression tests up to the limit of 8.0 kN. The stress gradients are measured with an optical device by birefringence. The research is aimed at determining the distribution and the values of stress gradients under tension and compression. The paper considers the problems of determining the stress values and their distribution in the glass plates with various stress concentrators, based on the results of non-destructive measuring, analytical calculations and the numerical simulation.

拉伸和压缩下带应力集中器的钢化结构玻璃的应力分布分析

本文描述了从带有三种不同类型的应力集中器的结构钢化玻璃板的拉伸和压缩实验测试中获得的结果，而没有使用它们。选择应力集中器的类型时应尽可能使其与实际情况下通常使用的应力集中器相近，并考虑到文献中已知的情况。所有测试均在相同的条件下进行，并加载1.0 kN的拉伸和压缩测试步骤，最大极限为8.0 kN。用光学装置通过双折射测量应力梯度。该研究旨在确定拉伸和压缩下的应力梯度分布和值。
