“…The cyclic (Han et al, 1995;Llorca, 1994;Sasaki et al, 1994) and monotonic (Corbin and Wilkinson, 1994;Llorca et al, 1991;Llorca et al, 1992) mechanical responses of metal matrix composites (MMCs) made up of a metal matrix and ceramic reinforcement have been much studied both numerically and experimentally in the literature. The compelling attention on such materials is due to their excellent combination of low density, high tensile strength, enhanced stiffness, high operating temperatures, wear and creep properties compared with the monolithic metallic counterpart (Suresh et al, 1993).…”

This paper investigates the cyclic plastic behavior of continuous fiber-reinforced aluminum matrix composites (CFAMCs) with different shape of fiber cross section arranged in a square packing geometry. The 2D micromechanical FEM models, composed of elastic undamaged reinforcement perfectly bonded to an elastic-perfectly plastic matrix with a volume fraction equal to 30%, are subjected to off-axis constant macro stress and a cyclic temperature history. Under such load conditions, the matrix undergoes large internal inelastic deformations potentially leading to internal crack initiation as well as macroscopic ratcheting. The computational method, the Linear Matching Method (LMM), is used throughout the analysis for the direct evaluation of shakedown, alternating plasticity and ratcheting behaviors. The effect of the matrix yield stress thermal degradation upon two common design limits, i.e., the reverse plasticity limit and the ratchet limit, is also investigated and discussed, including its influence on the off-axis low cycle fatigue crack initiation.

“…The development of metal matrix composites (MMCs) has set the stage for a new revolution in materials [1]. These composites have been developed to meet the demand for lighter materials with high wear resistance, high specific strength, stiffness, and heat resistance, and eventually used in many structural, tribological, and environmental applications [2].…”

“…Many applications for which these materials can be considered involve cyclic loading, and therefore, fatigue properties are of critical interest. It has been shown that the presence of reinforcements can increase fatigue life [2]. Koh, Oh [3] investigated the low-cycle fatigue (LCF) behavior of Al/SiC p composite and found that the composite and the unreinforced matrix alloy showed cyclic hardening behavior.…”

“…Koh, Oh [3] investigated the low-cycle fatigue (LCF) behavior of Al/SiC p composite and found that the composite and the unreinforced matrix alloy showed cyclic hardening behavior. Moreover, the fatigue endurance properties of SiC whisker-and particulate-reinforced composites show that the two forms of reinforcement have a similar effect; both composites are superior in high-cycle fatigue [2]. The improvement in the fatigue life of MMCs over conventional alloys has been ascribed to an increase in the number of cycles to initiate fatigue cracks [2,4].…”

The low-cycle fatigue (LCF) behavior, especially the fracture initiation mechanism in a cast hybrid metal matrix composite (MMC), was studied experimentally and numerically. The conventional three-point bending fatigue test was carried out and fractographic analysis was conducted to observe the fracture initiation site. Experimental results showed that microcracks in the LCF initiated at the particle-matrix interface which was located in the hybrid clustering region. Due to continued fatigue cycling, interface debonding occurred, created additional secondary microcracks and the microcrack coalesced with other nearby microcracks. As far as the numerical study is concerned, three-dimensional (3-D) unit-cell models of the hybrid MMC consisting of reinforcement clustering and non-clustering regions were developed by using the finite element method. The stress-strain distributions in both the reinforcement clustering and non-clustering regions were analyzed. The numerical results confirmed that the stress concentration occurred on the reinforcement-matrix interface located in the clustering region and provided reasonable agreement with the experimental observations.
