Sažetak
This paper shows the results of finite element (FE) models of three-layer particle boards. Two particle board FE models were made with differently defined structures. In the first model, the structure of commercial three-layer particle board is defined as single-layer with isotropic (PB-1L) properties, while in the second model, it is defined as three-layer with orthotropic properties (PB-3L). The results of FE models were compared with values obtained by testing the commercial particle board. Dimensions of FE models and applied loads were prepared according to bending strength testing mode defined according to EN 310:1993. Model comparison is based on comparison of sample deflection and von Mises stress in the middle of the sample. The analysis was done only in linear elastic region. The obtained results show that models with homogenous material (PB-1L) achieved greater agreement with measured results (deviation app. 2 %), while models with three-layer material (PB-3L) displayed deviation of app. 7 %. Lower agreement of results obtained for PB-3L model and measured values of commercial particle board is due to a greater number of approximations (elastic characteristics) involved in the simulation model. Despite the greater deviation, the preparation of a three-layer model would be more acceptable for the analysis of strain distribution across the cross-section of the particle board.
