Abstract

The edge strength of glass is affected by the load history: i.e. the load duration and the loading type, e.g. constant loading, cyclic loading or linearly increasing loading. In standards, these influences are expressed by the factor kmod, which reduces the strength depending on the load type, e.g. wind load, temperature load. In this study, five series of glass specimens with a cut edge finishing were subjected to in-plane four-point bending tests. First, the specimens were subjected to a linearly increasing loading. Then identical specimens were subjected to either a constant loading or a cyclic loading or both. These test results were compared to the theoretical prediction, based on the theory of fracture mechanics, as well as to the guidelines of the standards.
