If a textile yarn, marked at intervals along its length, is struck transversely by a rifle bullet, a flash photograph taken shortly after impact will reveal a shifting of the marks caused by passage of a strain wave. Analysis of these shifts provides

The behavior of an infinitely long flexible filament after transverse impact is treated theoretically. The filament is assumed to have a tension-strain curve which is always concave downwards and to have no short time creep or stress relaxation effec

A general mathematical solution to the problem of producing uniform abrasion over a plane area of a specimen from every azimuthal direction was worked out. This solution requires that the abradant and the specimen rotate in the same direction and wit

Equipment is described for elongating yarns by longitudinal impact at velocities rang ing from 10 to 100 m/sec. The rate of straining at impact varies from about 100,000 to 500,000% per min.A procedure is discussed for obtaining load-elongation curve

The behavior of a yarn specimen, which is fastened at one end to a head mass and at the other end to a small tail mass, is analyzed for longitudinal impact of the specimen at the head. The analysis leads to a basic formula for "limiting breaking velo

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 th

When a textile yarn is impacted transversely, strain waves and transverse waves which " travel outwards away from the point of impact are initiated. Each strain-wave front travels at constant velocity. A transverse-wave front, however, changes its ve
