Journal of Physics: Conference Series Vol. 1459. P. 012014 (1-6)Abstract: In the work, the problem of eccentric tension of a compact specimen with a crack was solved by numerical methods. It was proposed to use the results of numerical modeling for setting up and testing the original software package for measuring the deformation of materials by optical methods. The values of the fracture parameters obtained by software coincide with the experimental and numerical results. The proposed testing methodology made it possible to avoid problems with determining the error in the quality of calculation of the optical flow during verification. The dependences of the change of the values of stress intensity factor and J-integral on the applied tensile loading are determined for compact tension specimen with a crack from aluminum alloy D16.
