MODELING OF STRENGTH PROPERTIES OF STRUCTURAL PARTICLEBOARD 1

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 ofthe modellng techn~questhat can be fast and cosl-effecu\e Structural panlcleboard was modclcd tn lhls sludv as a multtlaver s\stem that consists of a number of l h ~ n and u n ~ t o m lavers that exhlblt . . different strength properties between layers, but the same properlies 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.
