Abstract
A model is proposed for predicting the nonlinear stress-strain relations and ultimate failure of ceramic minicomposites. Description of the micro-mechanisms which dictate the mechanical response (i.e. multiple cracking of the matrix and fiber failures) is based upon fracture statistics. The minicomposite specimen consists of a bundle of parallel fibers coated with a layer of interfacial material and a matrix. It is representative of the constituents in the actual textile composites.
Predictions from characteristics of the constituents, including the fibers, the matrix and the interphase, compared satisfactorily with the tensile force-strain curves measured on practical SiC/SiC minicomposites tested under uniaxial tension. Finally the influence of various constituent characteristics on the mechanical behavior was determined.
