内容記述 | The fracture energy of a polymethylmethacrylate resin plate has been measured by the cleavage method of experiment. To make the crack devlop exactly perpendicular to the loading direction without applying any retaining force, the specimen had a sufficient depth along the loading axis. Values of the fracture energy were computed following the Berry's method of analysis. Energy values in air at 20℃ and 40℃ were found to be, respectively, (0.923±0.045)×10^5 and (l.36±0.15)×10^5 erg/cm^2, and that in a mixed atmosphere of air and carbon dioxide at -5℃ showed a value of (1.62±0.07)×10^5 erg/cm^2. Cleavage experiment in water at 20℃ gave 3.0×10^5 erg/cm^2. All of these values are significantly smaller than those obtained by other authors. The fact that the values obtained in high temperature atmosphere and in water were higher than that in an ordinary temperature atmosphere should be related to the incidental formation of wrinkles at the crack front. | |||||
