Abstract: This paper has measured the dynamic modulus of elasticity ED of hardborad in different directions. The result indicates that dynamic modulus of elasticity ED of hardboard is of different properties in each direction: Maximum is in vertical direction, the second in across direction, minimum is when a is 30?
