Applying the Weakest-link rupture criterion of elasto-plastic frecture mechanics, the rupture modes of bamboo wood composite container flooring under bending loads were analyzed. Three-point bending test results demonstrate two kinds of rupture forms mainly, i.e. tension rupture o{ bottom layer and shear rupture of central layer. Based on the two cases, the theoretical predicting models of MOR for bamboo wood composite container flooring was developed. Adopting statistics regressive methods, the effects of the compression and gluing of veneers on MOR were researched, and mathematical correlative functions were also setup.
