Abstract | ||||
ABSTRACT In this study, fracture behavior of stainless steel/aluminum laminated composites with middle through thickness crack under fatigue loading, was investigated. The composite material, which has unidirectional continuous AISI 304 stainless steel as fibers and Al 2024 as matrix, was produced by using diffusion bonding. The fatigue tests were conducted under agreement with the ASTM E647 standard. The crack initiation, damage behavior, fatigue crack-growth rate (da/dN), stress intensity factor (ΔK), strain energy release rate (ΔG) and fracture toughness ( IC K ) were determined. Moreover, ΔG value was obtained by using Linear Elastic Fracture Mechanics (LEFM) and compliance methods and the results were compared with each other. Also, da/dN-ΔK and da/dN- ΔG were plotted for determining fracture behavior under fatigue loading of the composite material. | ||||
