WitrynaThe dynamic durability of wood is the ability to absorb impact bending (Požgaj et al. 1993). Impact is defined as the sudden collision of two bodies, the results of which depend on the strength of the impact force (Bodig and Jayne 1982). IBS tests were the historically first impact tests (Leijten 2004).

In mechanics, an impact is a high force or shock applied over a short time period when two or more bodies collide. Such a force or acceleration usually has a greater effect than a lower force applied over a proportionally longer period. The effect depends critically on the relative velocity of the bodies to one another. At normal speeds, during a perfectly inelastic collision, an object struck by a projectile will deform, … solheim cup monday tee timesWitrynaImpact bending test.
