Temperature and Axial Strain Rate Effects on Micromechanical Behavior in Triaxially Compressed Marbles

A series of high resolution, simultaneous stress-axial strain, volumetric strain, and acoustic emission measurements were used to survey the effects of temperature (T) and axial strain rate ((epsilon)) variations on micromechanical behavior in triaxially compressed marbles. Thirty-five tests were run on low porosity, homogeneous marble samples with relatively uniform calcite grain sizes (0.23, 0.50, and 1.90mm), at pressures (P) of 0.75, 1.375, and 2kb, temperatures of 30, 100, and 200(DEGREES)C, and computer-controlled strain rates of 10('-4), 10('-5), and 10('-6)/sec.
