ABSTRACT = {Digital image correlation (DIC) measurement technique and peridynamics (PD)
method have been applied in specific fields extensively owing to their respective advantages
in obtaining full-field deformation and local failure of loaded materials and structures. This
study provides a simple way to couple DIC measurements with PD simulations, which can
circumvent the difficulties of DIC in dealing with discontinuous deformations. Taking the
failure analysis of a compact tension specimen of aluminum alloy and a static three-point
bending concrete beam as examples, the DIC experimental system firstly measures the
full-field displacements, and then the PD simulation is applied on potential damage regions
determined according to the correlation coefficients, to track the micro-crack evolution and
macro-crack propagation. As results, the coupled DIC and PD approach can effectively
measure the full-field displacement and the localized damage accumulation and crack
propagation.
