Surface Crack Shape Evolution Modelling using an RMS SIF approach [PDF]

, 2010
The majority of fatigue cracks in thick plate and tubular sections in structural components are two-dimensional surface cracks having significant propagation lives before becoming critical.

Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]

, 2007
We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the

Three-Dimensional Singular Stress Fields and Interfacial Crack Path Instability in Bicrystalline Superlattices of Orthorhombic/Tetragonal Symmetries

Crystals
First, a recently developed eigenfunction expansion technique, based in part on the separation of the thickness variable and partly utilizing a modified Frobenius-type series expansion technique in conjunction with the Eshelby–Stroh formalism, is ...

A three-dimensional validation of crack curvature in muscovite mica [PDF]

, 2001
Experimental and computational efforts focused on characterizing crack tip curvature in muscovite mica. Wedge-driven cracks were propagated under monochromatic light. Micrographs verified the subtle curvature of the crack front near the free surface.

Complexity of crack front geometry enhances toughness of brittle solids [PDF]

Brittle solids typically fail by growth and propagation of a crack from a surface flaw. This process is modelled using linear elastic fracture mechanics, which parameterizes the toughness of a material by the critical stress intensity factor, or the ...

Assessment of three-dimensional crack growth in ductile layered material systems

, 2012
Fatigue crack growth in three-dimensions may follow complex patterns that depend on the local and global conditions of the material around the crack front.

Effects of planar crack distribution insemi-rigid base asphalt pavements

Case Studies in Construction Materials
During long-term service, semi-rigid base asphalt pavements are susceptible to surface cracking, cracking at the bottom of the base layer, and the resulting reflective cracking.
