Although the matter is not new, methods of processing the results are relatively recent. The article focuses on determination of crack length using DIC, however, the core of the work is the algorithm which determines the crack length based on the correlated point data. Results of optical measurement are compared to compliance-based analytical formulas. Altogether 18 experiments in radial orientation have been made. Samples used for determination of the strain energy release rate were 60 mm in width and 120 mm in height. Wider specimens have been used to employ the orientation of anatomical directions of the tested timber. Two cameras were used to track cracks on both sides. The algorithm works well, although interesting questions arise, especially when we look at the crack length determination algorithm and its failure criteria.
