Load-Deflection Analysis of Fibers with Plane Crimp

Abstract

An analysis is presented for the change in shape, due to bending and stretching of a coplanar crimped fiter subjected to static loading.For a fiber of given original con- figuration and specific loading, one may obtain the deformed configuration from the solution of two nonlinear differential equations.The load deflection relations are calcu- lated for a fiber with semicircular crimp and for three fibers with sine-wave crimps of different amplitude-wave length ratios.Reported also is an experimental verification of the results for two of the sine-wave crimps, using thin wire test specimens.'Present address.B Irgllll.1 I'(JI~ t('chllll' h)-.t!tute.H).t<!B-- hurg, B'a.~r i ,
