Abstract

An apparatus for measuring for measuring coefficient of restitution which is capable of reducing a mass effect and performing tests in free directions, is disclosed. The apparatus for measuring coefficient of restitution includes a holder for holding a spherical indenter, an ejection mechanism configured to eject the indenter held by the holder from the holder to a specimen, a speed measuring unit configured to measure an impact speed that is a speed of the indenter before the indenter impacts against the specimen, and a rebound speed that is a speed of the indenter after the indenter is rebounded from the specimen; and an arithmetic unit configured to calculate a coefficient of restitution that is a ratio of the rebound speed to the impact speed.
