Paper Abstract

Engineering components made of soda-lime glass sometimes contain notches with different shapes, particularly V-shaped notches. A V-notch plays the role of a stress concentrator that dramatically decreases the load bearing capacity of the component. Since fracture in soda-lime glass occurs suddenly due to its brittleness, it is necessary to estimate the fracture resistance of V-notched glass components under different loading conditions. In this research, the fracture behavior of glass components containing a rounded-tip V-notch was studied both experimentally and theoretically under mixed mode I/II loading. A wide range of mixed mode fracture tests were performed on the rounded-tip V-notched Brazilian disc specimens made of soda-lime glass. A mixed mode failure criterion was then used for predicting fracture initiation angle in the tested specimens. It was shown that the experimental results can be successfully predicted by using the results of the proposed criterion.
