The impact of porosity and crack density on the elasticity, strength and friction of cohesive granular materials : insights from DEM modelling

Schöpfer, Martin P. J. ; Abe, Steffen ; Childs, Conrad ; Walsh, John J. (Elsevier, 2009-02)

Empirical rock properties and continuum mechanics provide a basis for defining relationships between a variety of mechanical properties, such as strength, friction angle, Young’s modulus, Poisson’s ratio, on the one hand ...
Localisation of normal faults in multilayer sequences

Schöpfer, Martin P. J. ; Childs, Conrad ; Walsh, John J. (Elsevier, 2006-05)

Existing conceptual growth models for faults in layered sequences suggest that faults first localise in strong, and brittle, layers and are later linked in weak, and ductile, layers. We use the Discrete Element Method (DEM) ...
