ABSTRACT
In this contribution, ESPI and DIC are combined for strain analysis around a notch. The investigations are demonstrated using an epoxy notched cantilever bending beam. For the evaluation of the experimental raw data a special method is used, which includes parametrization of the notch surrounding region and optimized smoothing. Thus, the determination of more precise results of the ESPI and DIC analyses is enabled compared to standard evaluation procedures. The deformation measurement methods complement each other profitably, considering the respective limitations and potentials of ESPI and DIC.
