ABSTRACT

ABSTRACT:   A numerical study was undertaken to investigate the mechanical properties of metal-ceramic nanolayered composites. We utilized Aluminum (Al)/Silicon Carbide (SiC) alternating layers with same thickness as a model system. Finite element modeling was employed to analyze the microcompression behavior on pillars which consist 41 Al/SiC multilayers. It deformed in a non-uniform way under compression, especially when a tapered side wall included in the numerical model. Then elastic modulus was obtained from stress-strain curve and compared with previously calculated modulus value of the composite. It was found that the base material connected to the pillar plays a significant role in the measured mechanical response. The simulation result were also used to rationalize some of the experimental observations.
