A Statically Admissible Stress Field and an Admissible Displacement

The first fracture temporarily alters a stress field in the subterranean formation.

The approach couples a three-dimensional flow field and a one-dimensional stress field.

A polarization coupler includes a stress-inducing feature disposed to generate a stress-field in a substrate.

From the tangential stress components and radial directions of the at least three fractures, the stress field of the subterranean formation is determined.

The strain field is estimated from the data of displacement of the tracer grid.

A difference in velocity of the two acoustic waves is indicative of a stress field in the tubular.

These instruments impose a specific stress field or deformation to the fluid, and monitor the resultant deformation or stress.

First and second waveguides each a have a coupling portion that pass through the stress-field.

The second problem concerns the interaction of the three-dimensional stress field and the three-dimensional fluid flow field in rock.

Provided is a flexible anisotropic bonded NdFeB magnet with stress field orientation and fabrication method of same.

The mask structure, on the edges thereof, produces an elastic stress field in the layer to be structured and in the substrate.

An elastic strain field in generated in an already structured layer (22) and optionally in a substrate.

If the new internal stress field is such that there is compressive stress perpendicular to the direction of crack propagation, there is less probability that a crack 5 will propagate, and less probability that the object will break.

The more general approach, which couples a three-dimensional flow field and a three-dimensional stress field, was first considered by Biot (1941, 1955).
