fracture propagation

Fracture propagation is defined by the path a crack follows, and the degree of the crack's growth.

Pressure fluctuations, phase separation, and gold precipitation during seismic fracture propagation.

This is because long-distance fracture propagation may trigger avalanches on overlying slopes.

Sometimes, it is possible for fluids within the fracture to cause fracture propagation with a much lower pressure than initially required.

Key words: soil fracturing, laboratory test, low-permeability soil, fracture propagation.

Granitic magma transport by fracture propagation.

Tectonic earthquakes occur anywhere in the earth where there is sufficient stored elastic strain energy to drive fracture propagation along a fault plane.

Some have originated as chains of volcanic islands on the tectonic plates either as a result of mantle plumes or by fracture propagation.

Fracture propagation is the mechanism preferred by many geologists as it largely eliminates the major problems of moving a huge mass of magma through cold brittle crust.

The combination of seismic, gravity and ground deformation evidence suggests vesiculation and expansion of frothy magma and/or downwards fracture propagation and magma seepage.

By assuming fracture propagation will stop when the strain energy release rate is just greater than the fracture resistance, the width of a slab avalanche is found to be proportional to an arrest parameter.

Fracture Stimulation Modelling FRACPRO (RES): models fracture propagation, licence to be renewed when necessary (PCs).

Prof. O'Brien has published an extensive collection of research papers on topics such as surface reconstruction, human figure animation, mesh generation, physically based animation, surgical simulation, computational fluid dynamics, and fracture propagation.

Surface measurements of induced electrical potentials around a well which has been hydraulically fractured, carried out by Prakla-Seismos in Northwest Germany, established the direction of the hydraulic fracture propagation as being N.N.W.-S.S.E.

Whichever mode of deformation ultimately occurs is the result of a competition between processes that tend to localize strain, such as fracture propagation, and relaxational processes, such as annealing, that tend to delocalize strain.

Large compressive stresses parallel to the land (or a free) surface can create tensile mode fractures in rock, where the direction of fracture propagation is parallel to the greatest principle compressive stress and the direction of fracture opening is perpendicular to the free surface.
