Computer Simulation of Discrete Crack Propagation
Although statistical methods are widely used to study a large amount o f phenomena ranging from random walk to percolation and particle charging, the application o f these methods to mechanics is limited. Nevertheless the use of senses like fractal dimension can be very handy to describe the "mass" o f a crack or the roughness of a surface.

Numerical simulation study on the crack propagation of conglomerate [PDF]
The conglomerate reservoir is rich in oil and gas reserves; however, the gravel's mechanical properties and laws are difficult to gain through laboratory experiments, which furthermore constrain the hydraulic fracturing design. To analyse the failure law of conglomerate, we simulated the uniaxial compression test based on discrete element software ...
