Abstract:

This theoretical work deals with the mechanics of parallel fibre bundles, on the basis of the fact that each fibre in the bundle possesses different tensile behaviours. As a consequence of this, the tensile behaviour of a blended fibre bundle is found to be different than that obtained from Hamburger’s theory [3]. It is also observed that the average force per fibre in the bundle, the breaking force utilisation coefficient, and the breaking strain utilisation coefficient depend only on the coefficient of variation of the fibre breaking strain.
