| Tóm tắt: | Title screen The formation of strain inhomogeneity of zirconia ceramics have been studied during Brazilian test using a digital image correlation method. It was shown that with increasing load the deformation along the longitudinal axis was about 0.3%, and along the transverse axis less or equal to 0.12 %.The component of strain [epsilon][хх] and [epsilon][yy] has a non-uniform distributions on the sample surface and deformation of zirconia proceeds macroscopically localized. Coherently diffracting domains of the tetragonal phase and lattice microdistortion changes compared with the initial state after sintering and differ on different fracture fragments of the sample after its fracture. It was found that microstresses measured on different surfaces of fracture fragments of sample change in the range of 245-320 MPa, in accordance with the arising inhomogeneity of deformation. Strain localization correlates with inhomogeneity of the microstresses in the material during deformation. Режим доступа: по договору с организацией-держателем ресурса |
