Abstract
"The fracture behavior of a model brittle solid containing artificial surface flaws was studied. An industrial ceramic porcelain body was employed as the model brittle material. Sample groups of specimens containing 6, 11, 24, 49,. and 90 sharp surface notches uniformly distributed over a four inch length were broken under pure bending. The fracture data we-re compared to those of an identically treated control group containing no artificial flaws.
The mean strengths of the two groups of lowest flaw density were identical, both being significantly less than that for the control group. Further increases in flaw density resulted in increased mean strengths, exceeding fifty percent of the control group strength for bars containing 90 flaws. It was also found that the dispersion of experimental results was decreased markedly by the arrangements of artificial surf- ace flaws"--Abstract, p. ii
