Impact bending strength

WitrynaImpact bending strength was determined using a pendulum-impact testing machine (ALŞA, Istanbul, Turkey) at various span lengths, such as 10, 15, 20, 25, 30, and 35 cm. IBS was calculated using Eq. 1. After the test, the moisture content of the samples was determined, and the IBS values were corrected using the strength conversion, Eq. 2, … WitrynaThe dynamic durability of wood is the ability to absorb impact bending (Požgaj et al. 1993).
