A nanomechanical investigation of the crack tip process zone of marble
This study explores the interaction between crack initiation and nanomechanical properties in the crack tip process zone (zone of microcracking at the tip of a propagating crack) of a brittle geomaterial. Samples of Carrara marble with pre-existing cracks ("flaws") were loaded in a uniaxial testing …

The Effects of Load Ratio on Threshold Fatigue Crack Growth of Aluminum Alloys
… structures are threatened by the presence of cracks. Structural failure occurs if a crack larger than a critical size exists. Although most well designed structures initially contain no critical cracks, subcritical cracks can grow to failure under fatigue loading, called fatigue crack growth …
