| 内容記述 | Results of triaxial compression tests on ten dry rocks, including peridotite, diorite, granite, andesite, trachyte, tuff, and marble, are described and the pressure dependence of Young's modulus, plasticity, and strength are discussed. With an improved strain measurement, the load and the deformation were accurately measured without any frictional error. The deformation curve was obtained with a constant strain rate, but at some stages of deformation the differential stress was reduced to zero and again increased. By this cyclic loading test, the permanent strain was separated from the elastic strain, and Young's modulus was obtained from the mean slope of the unloading or reloading curve. These rocks also showed remarkable elastic hysteresis. Young's modulus, permanent strain, and elastic hysteresis were obtained as functions of the compressional strain and the confining pressure. The transition from brittle fracture to ductile flow and the pressure dependence of strength are also discussed. According to these experimental results, the mechanical property of rocks under confining pressure seems to depend mainly on porosity besides mineral composition. A preliminary experiment on the effect of previous loading is also described. | |||||

| 内容記述 | 前回にひきつづいて,各種岩石の高圧下の力学的諸性質を静的圧縮試験によつて調べた.今回は,変形測定法を改良することによつて,弾性領域から塑性領域にわたる,かなり広い変形範囲について,高精度の変形曲線を求めることができた.とくに,各変形段階で指圧を0にもどすことにより,弾性変形部分と永久変形部分を分離して求めた.かくして,弾性変形,塑性変形,弾性率及び弾性履歴などが,変形の進行と共に変化する渦程並びに静水圧との関係を求めることができた. | |||||
