Abstract

The critical stress intensity factor of mode I (K_Ic) obtained by single-edge-notched bending (SENB) tests of wood was experimentally and numerically analyzed. A double cantilever beam (DCB) test was also conducted and the results were compared with those of SENB tests. The K_Ic value was obtained by introducing an additional crack length into the equations used for analyzing the SENB test of isotropic material when the initial crack length ranged from 0.1 to 0.6 times the depth of the specimen.

Keywords: critical stress intensity factor of mode I; double cantilever beam test (DCB); finite element analysis (FEA); single-edge-notched bending test (SENB); virtual crack closure technique (VCCT)
