Statistical Theory of the Strength of Fiber Bundles
Journal of Applied Mechanics, 1983Following a review of statistical models of the failure of single fibers and bundles of these fibers, algebraic recurrence formulas are derived that generate expressions for the failure probabilities of bundles of classical fibers. One of these recurrence relations is suitable for the accurate numerical calculation of failure probabilities of bundles ...

Fiber Properties and Paper Fracture – Fiber Length and Fiber Strength
Trans. of the XIth Fund. Res. Symp. Cambridge, 1997, 1997Phenomenological theories on the effect of pulp fiber properties on the fracture energy of paper are discussed. The effect of fiber length and strength is clarified experimentally. Fiber length appears to affect fiber failure probability only slightly. When fiber strength is changed, the fracture energy decreases greatly with only a small increment in ...

Bend Strength versus Tensile Strength of Fiber‐Reinforced Ceramics
Journal of the American Ceramic Society, 1994The bending strength of fiber‐reinforced glasses and ceramics is often observed to be higher than their tensile strength; the difference varies, however, from one material to another. To gain an understanding of the relationship between these two measure of strength, we have carried out an analysis of bending which accounts for the deviations from ...

The study for strength calculation of one direction fiber-reinforced composites and the study measuring precisely fiber orientation distribution were presented. Need the systematic study for the data base that can predict mechanical properties of composite material and fiber orientation distribution by the fiber content was not constructed.

Metallurgical and Materials Transactions A, 1994
A series of single-crystal A12O3 fiber (Saphikon), reinforced Ni3Al-based composites were fabricated by a liquid metal infiltration technique, pressure casting. Tensile testing and indentation techniques have been employed to measure fiber strength and fiber/matrix interfacial debond shear stress.

The Strength and Weakness of Cotton Fibers
Textile Research Journal, 1951The structural reversals in cotton fibers are a preferred location of break when the fiber is ruptured in tension. With the aid of a polarizing microscope, observations were made of the fraction of fibers breaking at the reversals under various conditions of moisture content, specimen length, and chemical treatment.

Fine‐grained polycrystalline zirconia fibers have been formed from an acetate precursor. The fibers contained a Y 2 O 3 additive, which inhibited grain growth (grain size ≤0.5 μm) and allowed the tetragonal phase to be retained at room temperature ...

Commercially available graphite and ceramic fibers exhibit statistical strength distributions having separate Weibull moduli p' for the scaling of strength versus fiber length and p for the distribution of strengths across a collection of fibers at fixed length.

The Strength and Weakness of Cotton Fibers
Textile Research Journal, 1955Previous work has shown that the structural reversals of cotton fibers are points of weakness at which the fibers prefer to break. The present paper is concerned with the distribution of these reversals in the individual fibers and with differences in reversal frequencies for various cotton varieties.

Mechanics of Composite Materials, 2000
The relationship between the strength (σc) of unidirectional fiber-reinforced plastics in different stressed states and the interfacial strength of their components is investigated. The shear adhesive strength (τ0) of fiber—matrix joints determined by the pull-out technique is used as a measure of the interfacial strength.
