Numerical back analysis is a valuable tool available to rock mechanics researchers and
practitioners. Recent studies related to back analysis methods focused primarily on …

The macro-mechanical behavior of crystalline rocks including strength, deformability and
failure pattern are dominantly influenced by their grain-scale structures. Numerical …

Rock heterogeneities often control microcracking on the grain scale and therefore the
mechanical behavior of the rock on the macroscale. We therefore studied the fracture …

The emergent macroscopic behaviors of Bonded Block Models (BBM) are governed largely
by the properties assigned to their three components–blocks, contacts and zones (blocks …

The excavation of deep underground engineering causes a sophisticated three-dimensional
stress redistribution in the surrounding rock, leading to the damage and rupture of the …

The micro-geometric heterogeneity has a significant effect on the mechanical behavior and
failure mode of brittle rocks. To study the influence of the size distribution and preferred …

Macroporosity, pores or holes are common in rock mass, and play important roles on
mechanical behaviors of rock mass. The aim of the numerical study presented in this paper …

Rocks have inherently heterogeneous micro-structures. The mechanical response of these
heterogeneous micro-structures primarily governs the overall macroscopic behavior of intact …

A three-dimensional discrete element grain-based stress corrosion model incorporating the
theories of subcritical crack growth and chemical reaction rate was built to explore the time …

The impact of the width-to-height ratio (w/h ratio) on rock strength and deformation behavior
of rock pillars has been studied extensively since the 1950s through laboratory tests, in-situ …
