Textile research journal, Vol. 43, No. 12. Photographic investigation of high-speed missile impact upon nylon fabric. 1, Energy Absorption and Cone Radial Velocity in Fabric / Anthony F. Wilde
in Textile research journal / TRI/Princeton
Titre de série : Textile research journal, Vol. 43, No. 12 Titre : Photographic investigation of high-speed missile impact upon nylon fabric. 1, Energy Absorption and Cone Radial Velocity in Fabric Type de document : articles et extraits Auteurs : Anthony F. Wilde, Auteur ; David K. Roylance, Auteur ; Jos Ph M. Rogers Année de publication : 1973 Importance : p. 753-761 Langues : Anglais (eng) Mots-clés : Nylon fabric Missile impact broken orthogonal yarns High-speed photography Transient response interaction time fabric deformation cone cone radial velocity transverse wave velocity Missile energy loss energy partition fabric strain energy yarn breaking energy fabric kinetic energy energy transfer termination Fiber impact theory Résumé : Single layers of nylon fabric have been subjected to high-speed missile impact at velocities ranging from 116 to 537 m/sec. The transient responses of the fabric and missile have been observed by high-speed photography. The photo graphs have shown that fabric deformation was pyramidal before penetration and more conical after penetration. The photographs have permitted measurements of the missile exit velocity from the fabric, the missile energy loss due to interaction with the fabric, the time required to penetrate the fabric, and the size and growth rate of the resultant fabric deformation cones. These results, together with a simplified mechanical model, have indicated that the broken orthogonal yarns within the deformation cone could account for 50 100% of the observed missile energy loss. In addition, during penetration of the fabric, the measured average cone-radial velocities in the fabric ranged from 50 to 80% of the values derived from fiber impact theory.

Titre de série : Textile research journal, Vol. 44, No. 10 Titre : Photographic investigation of high-speed missile impact upon nylon fabric. 2, Retarding Force on Missile and Transverse Critical Velocity Type de document : articles et extraits Auteurs : Anthony F. Wilde, Auteur Année de publication : 1974 Importance : p. 772-778 Langues : Anglais (eng) Résumé : Investigation has been continued of missile impact (116 to 537 meter/sec) upon single layers of high-tenacity nylon fabric by further analyses of high-speed photographs described previously. The results have been compared with prior analogous experiments conducted with yarn bundles of similar material. It appears that the fabric interacts with the missile in a shorter time and along a smaller distance, resulting in a larger normalized retarding force on the missile than observed with the yarn bundles. Comparison of various specimen geometries of this material has led to an estimate of 600 to 650 meter/sec for its transverse critical velocity.
