In brittle materials containing pre-existing defects or fissures, failure typically follows a multi-stage process:
: In rock-concrete composites, interface dip angle and roughness govern where cracks form—either penetrating through both materials or forming along the interface. Analytical and Monitoring Techniques Strength Failure and Crack Evolution Behavior o...
: Larger confining stresses can inhibit simple splitting and lead to more complex, inclined failure planes or crushed edges. inclined failure planes or crushed edges.
