4. Conclusions

Damage detection method in the material based on the results of strain measurements by sensors, the locations of which are selected on the basis of numerical modeling of the stress-strain state, is presented. The results of the application of damage detection technique are presented using the example of a structurally similar angle shaped element made of glass fiber reinforced plastic using fiber-optic strain sensors based on Bragg gratings glued to the sample surface to measure strains. The results of numerical simulation and experiment demonstrate the possibility of recording the moment of appearance and development of defects associated with the local material failure in the specimen under consideration.
