This paper presents preliminary results of a study that is seeking to develop a stochastic finite element model to predict the global structural response when loaded in 4-point bending of different OSB panel designs based on the physical and mechanical properties. Experimental testing has been conducted to evaluate the physical and mechanical properties on a selection of OSB panels in a variety of thicknesses from three different producers. Statistical analyses have been conducted to establish the underlying probability distribution models to describe each property and regression analyses have been conducted to identify relationships between different properties. The results are being used as the basis for Monte Carlo simulation of input values for physical and mechanical properties for the numerical model. The observed structural response is being used to calibrate the model that in turn will be used to develop new, optimised OSB product designs.
