چکیده
|
The rocks in the studied area are prone to deterioration and failure due to frequent exposure to extreme temperature variations and loading conditions. in the context of rock engineering reliability assessment, understanding the energy conversion process in rocks is critical. therefore, this research work aims to assess the energy characteristics and failure modes of pink and white-black granite subjected to uniaxial compression loading at various temperatures. samples of pink and white-black granite are heated to a range of temperatures (0 °c, 200 °c, 400 °c, 600 °c, 900 °c, and 1100 °c), and their failure modes and energy characteristics including total energy, elastic energy, and dissipated energy are studied by testing preheated samples under uniaxial compression. the results show that the dissipation energy coefficient initially rises rapidly, and then falls back to its minimum value at the failure stage. the microstructures of granite rock directly affect its elastic and dissipation energy. axial splitting failure mode is observed in most of the damaged granite specimens. after heating granite to 600 °c, the effect of temperature on the failure mode becomes apparent
