This work aims to investigate the mechanical behaviour of medium-grained sandstones
under cyclic loading with different loading/unloading rates. This type of cyclic loading is …

During the process of mechanized excavation, rock is essentially subjected to cyclic point
loading (CPL). To understand the CPL fatigue behavior of rock materials, a series of CPL …

This article aims to investigate the impact of frequency sequence on mechanical responses
of sandstone exposed to multi-level compressive cyclic loading. Two modes were used with …

Stability of coal pillar (walls) is of great importance to security of underground mining.
Periodic excavation and water table variation subject coal pillars (walls) to cyclic load with …

Porous rocks exhibit mechanical behaviors characterized by high compressibility and
stiffness enhancement under quasi-static cyclic loads. In this study, we investigated the …

The artificial frozen wall crossing the water-rich sand layer is prone to failure during thawing.
To study the loading fracture characteristics and damage evolution of single-fissured …

The blast technology in metal mining is still the most important method of ore body mining.
With the increase of mining depth, the blast process is more and more affected by the rock …

This work strives to experimentally unveil the combining effects of freeze-thaw (FT) action
and differential cyclic loading (DCL) on the sandstone masonry. The cylindrical sandstones …
