The strength properties of structural particleboard are critically important factors. In designing a particular particleboard, a series of experiments can be run to determine the effect of a particular combination of factors. Modeling could be used as an alternative approach. Simulation modeling is one of the modeling techniques that can be fast and cost-effective. Structural particleboard was modeled in this study as a multilayer system that consists of a number of thin and uniform layers that exhibit different strength properties between layers, but the same properties within each layer. The effective modulus of elasticity of a board is a resultant of the combined effect of the modulus of all the layers. The modulus of rupture was obtained by determining the ultimate force or maximum moment during the simulated bending test. Internal bond strength was modeled using a modified regression equation.
