Identification of bearing failure in composite-aluminium bolted joints using digital image correlation

Integrated digital image correlation for mechanical characterization of carbon fiber-reinforced polymer plates

“…As previously described [21], CFRP plates are manufactured from the unidirectional prepreg material 6376/HTS. The material is cured, essentially to supplier specifications [22], in a pressurized autoclave.…”

“…In addition, a DIC measurement system was used to monitor the specimen during the whole loading sequence. In Paper I [6], DIC measurements are used to characterise initiation of failure of the CFRP plate in unsymmetrical single-shear two-bolt lap joints by observing the curvature of the specimen surface. In addition, data processing algorithms are developed in order to reduce the measurement noise and enable the calculation of second order derivatives of the measured displacements, which are needed to calculate the surface curvature of the specimens.…”

“…Stereo-DIC can perform measurements also on non-planar surfaces. When the displacements of surface points are known, it is possible to calculate other quantities such as strain and curvature, which is discussed in Paper I [6].…”
