 note = {An experimental study of damping characteristics of aluminum honeycomb sandwich beams is presented. Experiments were carried out under high temperature environments up to 240C. Test specimens were supported at their middle points and were excited in symmetric modes. Displacement of beams in damped free vibration was picked up and the logarithmic decrements and loss factors were calculated. From the experiments of many test specimens, the loss factors of sandwich beams have been obtained with high accuracy and the change of damping characteristics due to temperature rise has been clarified., 資料番号: NALTR0549000, レポート番号: NAL TR-549},
