| Abstract: | Referring to ISO13586-2000, a three point bending test （SENB）on the moso bamboo with initial cracks is conducted to study the tangential fracture behavior of moso bamboo mode I, with the value of the critical load PQ determined with the method of stiffness correction. The result shows that moso bamboo has good fracture toughness, with the average being 15.80 MPa·m^1/2. |
