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