Tóm tắt

The deformation and fracture of specimens of a carbon-carbon composite material with different dimensions of a stress concentrator in the form of a central hole with diameters of 7, 10, and 13 mm were studied using a developed combined method. The results of a numerical analysis of experimental data are presented in the form of diagrams (dependences) of the shear-deformation intensity and the acoustic-emission activity as functions of the loading time. The factors that cause similarity and differences of the investigation results are discussed and interpreted. It is proposed that the obtained data be used for the nondestructive testing of composite materials via the selection of characteristic stages of the deformation development and the moment that precedes fracturing.
