Abstract
Fractographic analysis of soda‐lime bars which failed under dead weight loading shows that the fracture mirror to initial flaw size ratio is a function of time under load, but that the mirror to critical flaw size ratio is a constant. The mirror constants are the same in delayed and rapid failure. The experimental results correlate with fracture mechanics predictions of time‐to‐failure based on subcritical crack growth. Scatter of the data about the prediction is discussed in terms of variations in flaw geometry.Keywords
