Abstract

The limitations of conventional methods of measuring strain are discussed in light of the structural composition of textile materials. The difficulties introduced in static and impact testing by stress concentration and strain inhomogeneity are considered. The need for twoโ€point strain measurement in regions of homogeneous strain is emphasized. A low inertia strainโ€measuring system utilizing magnetic tape is described as applied to tensile tests at jaw speeds of 1 to 100 ft./sec.

A method is proposed for in situ determination of the complex modulus of a member of an impact-loaded structure. The modulus was obtained in terms of strains measured at three different cross-sections of a uniform part of the member, by using one-dimensional theory. The potential of the method was e
