Abstract
This paper discusses how the behaviour on impact of textile yarns may be characterized in terms of such parameters as tenacity-strain data, breaking energy density, limiting breaking velocity, and critical velocity. Methods are given for obtaining the parameters from tests involving speeds of impact of 50 m/sec or less. At greater speeds of impact, strain-wave phenomena become appreciable, but the behaviour of the yarn may be studied by transverse impact methods. The results of a wave theory for transverse impact are given. The theory is then applied in a method for measuring longitudinal strain-wave velocity, and in two methods for obtaining tenacity-strain curves from high-speed transverse impact tests.Keywords
