The paper deals with numerical analysis of the DCB test configuration together with the data reduction scheme described in the ASTM D 5528 Standard for determination of the mode I fracture toughness in case of the laminated composites with mechanical couplings. The numerical analysis based on the FEM approach was performed with the Abaqus software exploiting the VCCT technique. The results show, that the distribution of the Strain Energy Release Rate can be asymmetric and that mode mixity can occur. A need for mode separation procedures and appropriate data reduction schemes has been revealed.
