摘要： A multi-layer composite synthetic test bed may be used to model fracture propagation and fracture networks. For example, a fracturing fluid may be introduced into a multi-layer composite synthetic test bed at a pressure and a flow rate sufficient to create a fracture network therein. Then, the fracture network may be analyzed to produce synthetic fracture data, which may be used in a fracture model.

摘要： Techniques and devices for measuring stress, strain, or temperature based on polarization crosstalk analysis in birefringence optical birefringent media including polarization maintaining fiber. The disclosed techniques and devices can be implemented to measure polarization crosstalk distribution in polarization maintaining fiber by placing the PM fiber in a 1-dimensional or 2-dimensional configuration for sensing temperature, stress or strain in the PM fiber at different locations along the fiber with a high spatial sensing resolution. In some implementations, the disclosed techniques and devices can be implemented to simultaneously measure stress, strain and temperature from analyzing the probe light. For example, both temperature and stress/strain can be simultaneously measured by using the same sensors to extract and separate temperature measurements from stress/strain measurements.

摘要： A photoelastic coating for structural monitoring of bridges, buildings, and other structures comprises an optically translucent or transparent photoelastic layer. The photoelastic coating is applied to the structure as a solvent-based liquid or gel. The photoelastic properties of the photoelastic layer are used to detect stress and strain or plastic deformation in the structure using photoelastic techniques. Also described is a method of structural monitoring comprising applying a photoelastic coating to a structure as a solvent-based liquid or gel. Presence of fringe patterns in the reflected light from the photoelastic layer indicates the presence of stress and strain in the photoelastic layer. Stress and strain in the photoelastic layer indicates stress and strain or plastic deformation in the underlying structure. The invention can be used for detecting when structures have been overloaded or when stress limits have been exceeded.

摘要： The present invention provides a tool for and method of using an infrared transmission technique to extract the full stress components of the in-plane residual stresses in thin, multi crystalline silicon wafers including in situ measurement of residual stress for large cast wafers. The shear difference method is used to obtain full stress components by integrating the shear stress map from the boundaries. System ambiguity at the boundaries is resolved completely by introducing a new analytical function. A new anisotropic stress optic law is provided, and stress optic coefficients are calibrated for different crystal grain orientations and stress orientations.
