Abstract

To predict accurately the failure load of a layered flakeboard in bending, the stress-strain relations appropriate for each layer must be known. This paper describes the application of a method for characterizing the nonlinear behavior of a flakeboard material subjected to axial stresses. The model permits prediction of the stress-strain curve to the ultimate stress and ultimate strain points for the material regardless of fiber alignment or board density. Comparisons are made between traditional failure criteria, experimental results, and the model predictions.
