Energy Storage and Dissipation Evolution Process and Characteristics of Marble in Three Tension-Type Failure Tests

Excerpt

Similar to investigations of failure mechanisms using the stress–strain relationship of rock materials, the energy analysis method, as a branch of the rock failure research methods, has already been applied to the field of rock mechanics and engineering applications because of its advantages in compensating for the deficiencies of classical elastoplastic mechanics theory (Thomas and Filippov 1999; Hua and You 2001; Wasantha et al. 2014). In addition, theoretical and experimental studies have confirmed that energy plays a highly crucial role in the process of deformation and destruction of rock materials (Bernabé and Revil 1995; Sujatha and Kishen 2003; Xie et al. 2004, 2005, 2009, 2011; Ju et al. 2010; Peng et al. 2015; Zhang and Gao 2015; Deng et al. 2016). The rock deformation and failure process can essentially be considered a process of energy storage, dissipation, and release (Xu et al. 2013). Hence, it is of great significance to further explore the range of rock energy-based research systems, and a macro–meso–micro system based on energy analysis has been suggested (Xie et al. 2004, 2005, 2011). …
