Using digital image correlation to automate the measurement of crack length and fracture energy in the mode I testing of structural adhesive joints

•A DIC method is proposed to measure the mode I crack length for adhesive joints.•Effective crack lengths including microscopic damage and root rotation effects were measured.•Crack length extended to the compression zone beyond the FPZ leads to the determination of accurate Gc values.•A method to c...
