摘要：
This invention relates to a method of determining the average plastic strain ratio (r) of sheet material of known density. This is effected by computation utilizing an empirical relationship existing for the material between r and an elastic property thereof, the elastic property being manifest as the velocity of mechanical vibrations propagated in the sheet.
