2 results about "Fracture testing" patented technology

The disclosure provides a crack analysis method, which can be applied to the technical fields of additive manufacturing and fracture mechanics. The crack analysis method comprises: determining a three-dimensional digital model of a biomimetic anti-fracture structure containing a designable hard fiber phase and a soft matrix phase feature; importing the three-dimensional digital model into the geometry preprocessing software of a material printing device for assembly to obtain a three-dimensional assembly model with the soft and hard phases adhered together; performing two-dimensional processing on the three-dimensional assembly digital model to obtain two-dimensional slice data containing the geometry of the soft and hard phases; importing the two-dimensional slice data into the material printing device for operation processing to obtain the optimal running track of the nozzle of the printing device and the type of material sprayed; layer by layer spraying and solidifying according to the optimal running track and the type of material sprayed to obtain a biomimetic anti-fracture structure sample containing a hard fiber and a soft matrix; performing a fracture test on the biomimetic anti-fracture structure sample, observing and analyzing the crack surface morphology and the fracture mode, and obtaining the observation results.

This invention relates to the field of hydraulic fracturing testing technology, and particularly to a fracture monitoring method, a brine hydraulic fracturing experimental apparatus, system, electronic equipment, and medium. The method includes: adjusting the concentration of the injected brine using a brine concentration control module based on a preset concentration curve, the concentration curve dynamically changing with experimental time or real-time multiphysics feedback data; during the hydraulic fracturing process of the injected brine, acquiring multiphysics data of the target fracture using a multiphysics monitoring module; and calculating the blockage state and salting-out degree of the target fracture using a multiphysics coupling analysis algorithm based on the multiphysics data. This approach solves the technical problem of existing technologies being unable to monitor the multiphysics coupling process under high temperature and high salinity conditions, improving the depth of research and the fidelity of experimental simulations regarding the fracture salting-out blockage mechanism during brine discharge from salt cavern-type compressed air energy storage.
