Cracking behaviors of rocks significantly affect the safety and stability of the explorations of
underground space and deep resources. To understand deeply the microscopic cracking …

Recently, the technique of nonlinear Lamb wave mixing has been developed for the
detection of fatigue crack in engineering structures. In this technique, two or three Lamb …

Water existing in micro-pores has tremendous influences on the mechanical and damage
characteristics of rocks. This study aims to investigate the micro-pore water effects on the …

Rock rupture refers to the process of crack initiation, propagation and coalescence. In order
to study the dynamic propagation and evolution process of internal cracks in rock subjected …

Researches on the fracture trajectory of pre-cracked specimen are mostly focused on
experiments and numerical simulations, and theoretical studies are usually limited to the …

Pore structures determine reservoir storage capacity, control rock transportation
characteristics and represent microscopic properties of the rock. Therefore, the …

The volume evolution behavior of rock fissures and the characteristics of acoustic emission
under cyclic loading are critical for rock stability analysis. To study the volume change …

This study proposes a novel approach to surface strain measurement for cylindrical rock
specimens subjected to uniaxial compression using distributed fibre optic sensing …

The increased intensity of dynamic disasters due to overlying burden in deep mining has
become a global issue. Understanding the spatial characteristics and governing principles …

The natural non-penetrated openings in natural rock masses due to weathering and erosion
and the artificial non-penetrated openings formed in deep mining and tunneling have …
