Interlaminar Fracture of Composite Laminates using Digital Image Correlation

Summary

The advent of optical strain measurement techniques such as digital image correlation (DIC), provide new opportunities to generate high resolution maps of the full-field of deformations and strains, revealing the pattern of deformation and damage throughout the specimen. DIC will be used for standardized fracture testing of FRP under mode I and mode II loading conditions, including a comparison of two types of standardized tests, revealing the critical strains as well as crack tip opening displacements in the vicinity of the crack tip as useful data for numerical cohesive zone models.
