FAILURE OF FIBER COMPOSITES - A LATTICE GREEN-FUNCTION MODEL

A new powerful numerical technique for investigating the failure of fiber reinforced composites is presented. The technique utilizes 3D lattice Green's functions to calculate load transfer from broken to unbroken fibers, and also includes the important eff ...

DETERMINING FIBER STRENGTH VS GAUGE LENGTH

William Curtin

This paper concerns the gage length dependence of fiber strength as established by measuring the fiber fracture stress vs. fragment length in the succession of fragments, which occur in tension testing of a single-fiber composite (s.f.c.). For fibers with ...

IN-SITU FIBER STRENGTHS IN CERAMIC-MATRIX COMPOSITES FROM FRACTURE MIRRORS

William Curtin

The in situ breaking stresses of pulled-out fibers on the fracture surface of a fiber-reinforced composite can be determined ex post facto from a measurement of the fracture mirrors on the surfaces of the fibers. Here, the relationship between the resultan ...

STRENGTH DISTRIBUTION OF CARBORUNDUM POLYCRYSTALLINE SIC FIBERS AS DERIVED FROM THE SINGLE-FIBER-COMPOSITE TEST

William Curtin

The single-fibre-composite (s.f.c) test, in which a fibre is embedded in an epoxy matrix and the composite tested in tension, was employed to obtain the statistical strength distribution of Carborundum SiC ceramic fibres over the range of gauge lengths fro ...

FIBER PULL-OUT AND STRAIN LOCALIZATION IN CERAMIC MATRIX COMPOSITES

William Curtin

THE MECHANICAL properties of ceramic matrices uniaxially reinforced with strong continuous fibers depend on a wide variety of material parameters: the fiber and matrix elastic moduli, the matrix toughness, the statistical fiber strength, the fiber radius a ...

MECHANICAL-PROPERTIES OF CONTINUOUS-FIBER-REINFORCED CARBON MATRIX COMPOSITES AND RELATIONSHIPS TO CONSTITUENT PROPERTIES

William Curtin

The tensile properties of three carbon matrix composites reinforced with SiC (Nicalon) fibers (materials A, B, C) have been measured with and without notches. One of the three materials (material B) had a relatively low strength and exhibited notch brittle ...

ALGEBRAIC SCALING OF MATERIAL STRENGTH

William Curtin

The strength of a brittle material is determined by the extreme tail of its crack-size distribution. The Weibull ansatz of algebraic distributions has been widely used but is not derived from any physical mechanism, and recent results on randomly depleted ...

THEORY OF MECHANICAL-PROPERTIES OF CERAMIC-MATRIX COMPOSITES

William Curtin

A theory is presented to predict the pullout work and ultimate tensile strength of ceramic-matrix composite (CMC) materials tested under uniaxial tension as functions of the underlying material properties. By assuming that the fibers fracture independently ...

FIBER FRAGMENTATION IN A SINGLE-FILAMENT COMPOSITE

William Curtin

The fiber fragment distribution obtained from tensile testing of a single-filament composite contains vital information on the in situ strength of the fiber at short gauge lengths and on the shear stress across the fiber/matrix interface. Here, this fragme ...

EXACT THEORY OF FIBER FRAGMENTATION IN A SINGLE-FILAMENT COMPOSITE

William Curtin

An exact theory is developed to describe the evolution of fibre fragmentation in a single-filament composite test as a function of the underlying fibre statistical strength and fibre/matrix interfacial shear stress, tau. The fragment distribution is a comp ...
