Paper presented at the ISRM International Symposium on In-Situ Rock Stress, May 10–12, 2016
Paper Number: ISRM-ISRS-2016-037
... and Technology (AIST), Japan related to earthquake prediction, an attempt to determine three-dimensional stress tensor was carried out. We successfully applied the corebased method called anelastic strain recovery (ASR) method for two core samples retrieved from a depth of approximate 470 m in the Niihama...

... to verify this method. The shore-based verification and calibration experiments were carried out on the same three core samples used for the onsite measurements. Calibration experiments consist of two steps: K 0 consolidation using a triaxial compression test system, and then ASR measurement using...

... ABSTRACT: To determine three-dimensional stress orientation, we carried anelastic strain recovery (ASR) measurements out using drill core samples taken from a scientific ocean deep drilling project. The lithology of the core samples is mudstone or siltstone with larger porosities ranged from...
