Abstract

Wave propagation in damageable media and the evolution of damage due to repeated impact during percussion drilling in brittle disordered materials is investigated.

Analytical, numerical and experimental work complementing each other in clarifying the complex dynamic process of damage evolution and fracture network development in polycrystalline brittle materials is presented. Upon field tests rock samples have been sectioned and a microscopic investigation of the damage and fracture zone at the bottom and the circumference of the bore hole has been performed.

Based on experimental findings a three-dimensional numerical simulation scheme has been developed which incorporates wave propagation in dissimilar granular arrangements, dynamic impact phenomena and accumulation of brittle damage of rock grains.
