| dc.description | An apparatus is described which is suitable for measuring the flexural damping and dynamic Young's modulus of beam specimens at stress levels up to 200 MN m<sup>−2</sup>. Symmetric free-free flexural modes of vibration are excited by a coil/magnet pair, the coil being attached to the midpoint of the beam. Extraneous sources of damping have been reduced to a low level despite the difficulties of producing high-amplitude vibration. Low-damping specimens must be tested in vacuo (0·5 Torr was usually sufficient) if the effects of air damping are not to be significant. Specific damping capacities from 0·1 to 50% can be accurately measured over a frequency range of 100 to 800 Hz and a temperature range -50 to +200°C. |
