This paper presents results of fracture toughness tests on DCB specimens made of natural and modified pine wood. The energy release coefficients G�[alfa] were calculated for both the materials under TL and RL crack propagation modes and the 1st mode of loading. Relations between the energy release coeffcients G�[alfa]I and the stress intensity factors K�[alfa]I have been determined. The obtained test results are presented in the form of tables and diagrams.
