A stochastic model based on the Langevin equation was used to describe crack paths in composites. A single crack path in a fiberglass reinforced epoxy matrix composite was used to predict Langevin parameters quantifying architectural drift and materi

A Monte Carlo model of the effects of fiber creep in a 0°/90° plain weave ceramic-grade Nicalon reinforced SiC composite has been developed. Creep degradation of fibers was predicted to result in stress dependent premature failure of woven ceramic

The elevated temperature response resulting from tensile creep of fiber reinforced ceramic composites was modeled using Monte Carlo simulation. The model consisted of a uniaxially loaded fiber tow aligned with the direction of applied load, and model

Monte Carlo simulation has been used to model environmental attack of a fibre tow, and suggested that such attack could lead to fatigue-type behaviour under static load conditions. The system was assumed to be fibre dominated with the presence of mat

Fatigue of reinforced ceramics at elevated temperatures was numerically evaluated with a fiber dominated, power-law creep model. A Monte Carlo simulation of fiber creep in a uniaxially loaded tow was used to examine the influence of fiber radius, ela

A numerical simulation that predicted fatigue-like behavior resulting from chemical attack of bridging fibers in a cracked composite was developed. Chemical attack of bridging fibers led to mechanical failure of bridging fibers, and a corresponding r

Oxynitride glass (Al 2 O 3 · ( 3 2 ) Y 2 O 3 · ( 3 4 ) SiO 2 · ( 3 4 ) Si 3 N 4 ) has exhibited subcritical crack growth when submerged in deionized water. Crack velocities ranging from 10 −7 to 10 −5 m/s were observed for applied stress inten

Time-dependent failure at elevated temperatures currently governs the service life of oxynitride glass-joined silicon nitride. Creep, devitrification, stress-aided oxidation-controlled slow crack growth, and viscous cavitation-controlled failure are
