The paper is concerned with an investigation of the relationship between withdrawal force and pulling speed of a single fiber from parallel fiber bundle in a channel, subjected to external load.
Experimental apparatus which modified those of Postle-Ingham s2), are shown in Fig. 3_??_1. Experimental materials are 3 denier viscose rayon Fibres.
When the values of applied load R and pulling speed υ are fixed, observed valuse of the withdrawal force f are distributed broadly, for example, as the curves in Fig. 3_??_8. From the experimental results (see Table I) the following relationship between mean withdrawal force fm and pulling speed υ are obtained:fm=AlogBυWhere parameter A and B are functions of applied load R.
In this paper, also, the relation (3_??_8)′ are discussed theoretically, based on the stochastic process theory of breaking phenomena of matter.4)
