    Abstract - (Show below) - (Hide below)

    Describes a method for the determination of the flexural modulus by using experimentally measured natural frequencies in the free-free mode of transverse vibration of cylindrical paper and board cores, which meet the following criteria: - internal diameter: 50 mm to 350 mm; - minimum wall thickness: 0,02 x internal diameter or not less than 2,0 mm; - minimum length of core: 8 x internal diameter.
