摘要: This study was conducted to explore the effect of repeated loadings and vibration on bending properties pallet deckboards. Pallets were fabricated from three common hardwood species : white oak, red yellow-poplar. with 10 deckboards each subjected a 1,500-pound load resonant for hours then an additional 5 determine if any change occurred in boards. After loading treatment, boards nondestructively tested modulus elasticity (MOE). These measurements compared initial MOE In addition, final rupture (MOR) MOR matched samples. Results showed that average all samples did not significantly. Also, values, before after vibration, significantly different.
