“…The proportion coefficient in this linear relationship is an empirical parameter, which varies considerably with loading condition, and has no explicit meaning. The shapes of the FCP a-N curves predicted by this methodology are different with those from other test data for the same aluminum alloy [10,11,17].…”

“…[11], cracked 2024-T3 aluminum alloy members with a CCT geometry and nominal thickness of t = 2.29 mm and t = 6.35 mm, reinforced with a glass/epoxy composite patch, were investigated. The typical geometry and loading of such a specimen are shown in Fig.…”

“…Some analytical and experimental researches have investigated the fatigue crack propagation (FCP) behavior of cracked metallic members repaired with a single-sided or double-sided composite patches [5,8,9,11,14,15]. The numerical studies for this problem have mainly focused on the determination of stress intensity factors in the cracked panels through calculating the strain energy release rate.…”

a b s t r a c tThe concept of fracture for material elements at front of a crack for fatigue crack propagation was extended to the fatigue crack propagation of a cracked metallic member reinforced with a composite patch in this paper. From static mechanics and linear elastic fracture mechanics, force transfer on a cracked member through a composite patch was analyzed and a formula connecting the stress intensity factor with crack length was obtained. Thereafter, a fracture model for fatigue crack propagation of a repaired cracked metallic member was proposed. A new expression for the fatigue crack propagation rate has thus been derived. The expression was verified objectively by the test data. It is in good agreement with the test results.Crown
