Dynamic behavior of wood strip over elastic underlayment composite flooring subjected to light impact loads

Summary The dynamic behavior of composites consisting of wood flooring strips placed over rubber sheeting was investigated. A light impact load was applied to the center of the strips and impact force, contact duration and contact area were measured. The energy transfer from the impacting mass to the composite was estimated by measuring the restitution coefficient. Frequency analysis was conducted in order to examine the vibration characteristics of the composites.This study was carried out at the Forest Products Laboratory, University of California at Berkeley while the first author was a visiting scholar supported by the Science and Technology Agency, Japan
