About

Crack Monitoring in DCB under Mode II fracture. This movie shows the application of crack monitoring technique using FBG sensors in a DCB specimen under Mode II fracture. It is showed the reflected spectrum from the FBG array, a picture of the specimen during the test, and the DIC results, synchronized with the wavelength shift Δλb and peak width variation ΔλWV results computed during the test. The movie is divided in two parts: in the first part the DIC technique shows the negative component of the strain field in the y direction, ɛy; in the second part the DIC technique shows the strain field in the x direction, ɛx.
