High-strain-rate tensile behavior of sedimentary and igneous rocks at low temperatures / Piyush K. Dutta, Kunsoo Kim.

Title: High-strain-rate tensile behavior of sedimentary and igneous rocks at low temperatures / Piyush K. Dutta, Kunsoo Kim.
Author(s): Dutta, Piyush K.
Kim, Kunsoo.
Date: 1993.
In: CRREL Report. (1993.), Vol. 93-16 (1993)
Abstract: Aim was to develop better understanding of mechanics of fragmentation of rocks in impact crushing at low temperatures, focusing on tensile failure in intact rock specimens (limestone and granite) of disk shape resulting from diametral impact loading. Test results were compared with those obtained from quasistatic tests; mechanism of failure under dynamic loading by stress waves was found to be significantly different, producing multiple fractures, absorbing more energy, and, because of cushion of broken rocks produced beneath loading surface, requiring higher loads for complete failure. Influence of low temperature was less dramatic, but, in all cases, strength increased with decreasing temperatures.
