摘要：
The applicability of various criteria for evaluation of the fracture toughness of a discretely reinforced carbon-carbon composite material for friction purposes is considered. The values of the K-1c, J(1c), J(c) and COD criteria of fracture toughness are calculated. The distribution of the fields of displacements and deformations on the surface of specimens is determined by the method of numerical correlation of digital images with the use of a VIC-3D system. The stress fields are calculated.
