Sentence examples for main fracture surface from inspiring English sources

The main fracture surface formed nearly parallel to the plane of the existing healed fracture.

When the horizontal principal stress difference is small, the main fracture surface is parallel to the laminae strike, and the primary fractures will propagate as follows: propagate through the laminae, then deflect significantly at the surface of the laminae, continue along the laminae surface and finally change direction and propagate again through the laminae.

A new method is proposed to calculate the fractal dimension of the fracture surface, and based on this method, it is found that the fractal characteristics of the main fracture surface of the red sandstone specimen show that the fractal dimension along the shear direction increases first and then decrease, and appears maximum value in the middle.

When the horizontal principal stress difference is big, the main fracture surface is perpendicular to the laminae strike and the primary fractures will propagate as follows: run through the laminae, change their propagation direction dramatically on the laminar surface, and then run through the laminae.

Meanwhile, compared with the water fracturing, it is implied that the breakdown pressure of SC-CO2 is generally lower, and its tortuosity of the main fracture and roughness of the main fracture surface tend to be higher under the same experimental conditions.

Electron microscopy analysis revealed evidence of an environment-assisted failure with extensive secondary cracking near the main fracture-surface.

The modelling results show that particle-particle friction angle, particle-fiber friction angle, fiber tensile strength, D90 degradation rate, and friction angle between plugging zone and fracture surface are main mechanical parameters affecting the plugging zone strength.

Due to the developed facture networks of brittle shale in this region, frictional sliding along the fracture surface is the main source of movement within the Longmaxi Formation.

The fracture surface analysis demonstrated that the main fracture mode was transgranular, indicating the existence of a strong Al2O3 network in the in situ synthesized composites.

The fractographic analysis showed delamination and clusters of pulled-out fibers as the main fracture characteristics, and that the fracture initiates at the internal surface of the rings.

SEM fracture surface observations allowed analyzing, at the local scale, the main deformation mechanisms occurring during mechanical loading.
