对木材单边缺口弯曲试验得到的I型临界应力强度因子(K(IC))进行了实验和数值分析。进行了双悬臂梁(DCB)试验，并与SENB试验结果进行了比较。当初始裂纹长度为试件深度的0.1~0.6倍时，通过在用于分析各向同性材料的SENB试验的方程中引入附加裂纹长度来获得K(IC)值。
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.
