“…Most of the experimental characterization of the mechanical behavior of continuous unidirectional alumina fiber reinforced aluminum that has been reported in the literature has focused on studies of the strength and deformation mechanisms of the composite loaded along the fiber axis. Compressive [23][24], tensile [25][26][27][28], bending [25], and fatigue [29] properties have been reported for loading applied along the fiber axis of unidirectional alumina fiber reinforced aluminum. Hall et al [30] studied the quasi-static and high strain rate properties of cross-ply unidirectional alumina reinforced aluminum MMC and found that the properties were strongly dependent on fiber distribution and alignment.…”

Continuous unidirectional ceramic fiber and woven fabric reinforced metal matrix composites (MMCs) have potential to obtain very high specific strengths and stiffnesses, but use in structural applications has thus far been limited by their inherently low ductility, particularly in tensile loading conditions. In this work, a multi-scale micromechanics based finite element framework is used to predict, and understand the effect of microstructure on the tensile deformation behavior, including progressive damage and failure, of ceramic fiber and fabric reinforced MMCs. A hierarchal approach is implemented in which a micro-scale model is used to determine the transversely isotropic elasto-plastic mechanical behavior of unidirectional fiber reinforced MMC based on the properties of an aluminum alloy matrix, individual ceramic fibers, and the fiber-matrix interface. The validated transversely isotropic constitutive behavior is then input into a unit cell model for a woven fabric MMC consisting of unidirectional MMC tows in

“…Some basic investigations about the fatigue behavior of continuous fiber reinforced light metals have been done by Baker, [7] Moser et al, [8] and Bettge et al [9] on silica and steel fiber [7] as well as on alumina fiber [8] reinforced aluminum and aluminum alloys, whereas ref. [9] focussed on silicon carbide reinforced titanium.…”

In the field of lightweight construction for transportation means, hybrid structures composed of highstrength and low-density materials exhibit a high potential for application. The composite extrusion process allows an easy embedding of metallic reinforcements into a multitude of light metal alloys. The current work shows that different metallic wire reinforced light alloys with a content of 11.1 vol% lead to a significant increase in lifetime of different aluminum and magnesium alloys under fully reversed stress controlled fatigue loading. Based on the knowledge of the quasi-static behavior of the single components and the fatigue behavior of the matrix material, a new lifetime model is used to predict the lifetime for different unidirectionally reinforced material systems.

“…They reported that the bilinear stress versus number of cycles (S-N) model provides a much better representation of the data than the commonly used linear model for AI alloys. Moiser et al [13] investigated continuous alumina fiber reinforced aluminum composites under fatigue loading. Their experimental results showed that gradual fiber fractures were observed as the number of cycles increases.…”

Fatigue crack growth and related damage mechanisms were investigated experimentally in a stainless steel/aluminum laminated composite with middle through thickness crack, and two different fracture mechanics approaches applied to the composite to reveal their differences under fatigue loading. The laminated composite material, which has a unidirectional continuous AISI 304 stainless steel as fibers and Al 1060 as matrix, was produced by using diffusion bonding. Fatigue tests were conducted in accordance with ASTM E 647. The relationships between fatigue crack growth rate (da/dN), stress intensity factor (AK), and strain energy release rate (AG) were determined; and damage behavior was discussed. Both linear elastic fracture mechanics (LEFM) and compliance method were used, and the results were compared with each other. It is found that as the crack propagates, the LEFM overestimates the AG values. Interlaminar and fiber/matrix interface damage were evaluated by fractographic examination.
