EXPERIMENTAL STUDY OF FATIGUE PERFORMANCE OF TEMPERED GLASS PANELS UNDER CYCLIC LOADING

摘要

The strength of the material is dependent on the distribution of cracks or surface flaws. These factors, coupled with the inherent brittleness, complicate the fatigue strength of tempered glass panels. This paper is concerned with fatigue performance of tempered glass panels under cyclic loading in room environment. It was found that the fatigue strength of glass panels depend very strongly on their static strength. And the experimental results give the evidence that they deserve the same high degree of scatter of strength. However, the linear S-N curves were used to fit the experimental data, and the Goodman method was employed to approximately account for the effect of mean load.
