| 英文摘要 | Fractographers’ qualitative measurements of the mirror radii are routinely used to estimate the fracture strength of brittle materials. Different imaging methods, magnifications, and observers’ subjective length-estimates are expected to affect the strength predictions, but their relative influence was never quantified prior to this work. In this manuscript, 31 aluminosilicate glass plates were fractured by four-point bending (strength range: 71-117 MPa) and eight observers independently estimated the mirror radii per ASTM Standard C1678-10. The effects of magnifications, imaging methods, and observers were then quantified. It was found that these effects account for up to 6% of the estimate's error (i.e., the estimate bias) on the average. Additionally, random variations in the range of ±3% to ±4% are expected. Furthermore, it was shown that using the fracture surface's profilometry scans, aided by the analytical knowledge of the shape of the mirror-mist boundary, could eliminate the bias and significantly improve the accuracy of predictions. © 2018 Elsevier Ltd |
