This paper aimed at evaluating the effect of fatigue through different loading cycles (20,0000; 40,000 and 80,000 cycles) on deflection and flexural properties of commercial MDF and particleboard panels. A 2.2 seconds (0.45 Hz) cyclic loading was employed and the applied load about 25% of modulus of rupture was used. After the tests, final deflection (with load), residual deflection (without load) and flexural properties of the panels were evaluated. According to the results, the flexural properties for both kinds of panels were not affected by the loading cycles tested. However, it was identified that the MDF residual deflection was affected between 20,000 and 80,000 loading cycles.
