We have investigated the stress state of models of beams with damage in the form of cuts, simulating the vertical and inclined cracks. The experiments were performed in pure and direct lateral bending. The crack was located in the tension zone model of a beam of piezooptical plexiglass. To study was used method of the photo elasticity. Was ended collating of the stress fields in models of beams with reinforcing layer of carbon fiber and in its absence.
