Lerner-Lam noted, " there is evidence that a large nuclear explosion can change stress fields in the earth's crust ."
32.
Zobacks'major area of interest is active tectonics, with emphasis on the relationship of the in-situ tectonic stress field to earthquake deformation.
33.
As dislocations generate repulsive stress fields, each successive dislocation will apply a repulsive force to the dislocation incident with the grain boundary.
34.
In addition, there is a positive interaction energy between a dislocation and a precipitate that have the same type of stress field.
35.
Hence, the more dislocations are present in a grain, the greater the stress field felt by a dislocation near a grain boundary:
36.
When solute and solvent atoms differ in size, local stress fields are created that can attract or repel dislocations in their vicinity.
37.
The characterization of flow or deformation originating from a simple shear stress field is called shear rheometry ( or shear rheology ).
38.
The Gulf of Mexico is tectonically passive with low shear strength, but seaward slumping has produced a weak but mappable stress field.
39.
Intuitively, one can picture the stress fields as the stress created by adding an extra half plane of atoms to a crystal.
40.
Since both events involved significant north-south shortening, deformation is said to have occurred in response to a similarly oriented in-plane regional stress field.
