This study investigated the influence of temperature on the mode I fracture toughness of
sandstone using semicircular bend specimens. Fracture characteristics were studied using …

The physical, mechanical and morphological properties of a rock undergo substantial
change when exposed to the extreme temperatures that are encountered in processes such …

To study the fracture toughness of sandstone, this study investigated the influence of
temperature on the mixed-mode (I+ II) and mode-II fracture toughness of sandstone using …

Abstract Knowledge of the variations caused by high temperature to the mechanical
properties is a vital asset in processes such as underground coal gasification (UCG), in-situ …

Mechanical properties of reservoirs and overlying strata in the condition of underground coal
gasification (UCG) are vital to the stability of surrounding rock. In this work, sandstone …

Study of rocks under high temperature and strain-rate condition can serve as vital
information in the restoration process of fire damaged buildings. In this study, the …

Studies conducted by several researchers suggest that a large variance exists in the
morphological integrity of rocks when subjected to thermal treatment. The extent of thermal …

Failure to properly characterize time-dependent behavior (ie creep) of rocks and the use of
inappropriate behavior models when analyzing stability of underground spaces such as …

This paper experimentally studies the evolution of absorption energy characteristics per unit
thickness of Jhiri sandstone at variable temperatures (from 25 to 900° C), each specimen …

The mode I fracture toughness is a critical parameter which defines the rock's resistance to
crack propagation, especially in hydraulic fracturing. Recently, Supercritical carbon dioxide …
