The acoustic emission (AE) and the mechanical behavior of granite samples during triaxial
compression tests have been analyzed. The size of AE events displays power law …

Stress waves, known as acoustic emissions (AEs), are released by localized inelastic
deformation events during the progressive failure of brittle rocks. Although several numerical …

Numerical simulations using the 3D discrete element method can yield mechanical and
dynamic behaviors similar to rocks and grains. In the model, rock is represented by bonded …

At the microscopic scale (say, of the order of grain size), rock is a heterogeneous material
whose brittle fracture is a complicated progressive process caused by isolated …

To better investigate the cracking processes under uniaxial compression, a numerical
approach using bonded-particle model (BPM) was adopted to simulate the loading …

The seismogenic process is nonlinear and irreversible so that the response to loading is
different from unloading. This difference reflects the damage of a loaded material. Based on …

Development of brittle fracture and the associated macroscopic behaviour of rock specimens
in laboratory tests are simulated using a local degradation model for brittle fracture in …

Intermittent jointed rocks, which exist in a myriad of engineering projects, are extraordinarily
susceptible to cyclic loadings. Understanding the dynamic fatigue properties of jointed rocks …

Rocks containing unparallel fissures are likely to be subjected to dynamic loading resulting
from earthquakes in various civil engineering structures. Since dynamic loading rate …

Abstract Ceramic Matrix Composites (CMC) are advanced materials composed of ceramic
fibers embedded in a ceramic matrix, resulting in a highly durable and lightweight composite …
