Abstract:

Within the framework of research work carried out at the Institute of Papermaking and Printing, the Technical University of Łódź, Poisson’s ratios were determined in a paper plane. This feature presents a simple and easy method how to determine this material constant. The method proposed for the determination of Poisson’s ratio utilises the results of typical procedures used when defining physical properties, such as Young’s modulus, paper density and the TSI (tensile stiffness index). For practical verification of the method proposed, the author tested papers for the production of corrugated board and compared the values of ratios obtained for the propagation velocity of sonic waves in the machine and cross directions.
