dc.description.abstract Effects of post-ion exchange abrasion on strength and fatigue of soda-lime silicate glass rods, were determined using four-point bend tests. Dynamic fatigue tests were carried out by varying the strain rate over 2 orders of magnitude in air or after a short immersion in water. Ion exchange was carried out at 450ᵒC for 4 or 16-hours. Following the ion exchange treatment, the glass rods were abraded using sand particles between 212 to 149μm and 106 to 63μm. The resulting strength (MOR) values were plotted using Weibull statistics. Dynamic fatigue plots showing the effect of stressing rate on strengths were also plotted, and the slow crack growth constant (n) was determined for each combination of ion exchange time and post-abrasion. Results indicate that the surface stresses induced by chemical strengthening reduces effects of stress-induced slow crack growth. However, anomalous, and unexpected large reductions in fatigue behavior requires that additional measurements, be carried out before any interpretations can be provided. en_US
