Analytical calculation of fracture toughness of materials on tests of small-sized samples with a chevron notch
On the example of technical titanium VT1-0, a new technique for determining the crack resistance of materials is described in the data of tests of small-sized samples with a chevron notch. The problem of displacement the points of application of the part load due to the variation in the compliance of the sample during the propagation of a crack is solved. Equations for the calculation of the specific fracture energy from the experimental data of small-sized samples with a chevron notch are obtained
