AbstractA three-dimensional micromechanical finite element model is developed to study the effects of a manufacturing environment on thermal residual stresses in a SiC/Ti-6Al-4V metal-matrix composite. The model includes a representative volume element consisting of a quarter of SiC fiber covered by relatively thick coating and an interaction layer all of which are surrounded by the Ti-6Al-4V matrix. Stress relaxation due to the viscoplastic behavior of the matrix is accounted for different manufacturing environments, that is, air and nitrogen. The results show that the presented model provides accurate predictions when compared with experimental data. It is possible to use the presented results for appropriate selection of manufacturing parameters. The results suggest that to delay the onset of interface debonding, the best choice is to use cooling rates higher than 0.64 and 0.1°C/s, respectively, for air and nitrogen environments. In order to use simple elastic-plastic models to predict residual stresses within the composite, detailed equivalent stress-free temperatures for various environments, cooling rates, and fiber volume fractions are presented.

AbstractIn this work, the finite element method was used to determine the stress intensity factors as a function of crack propagation in metal matrix composite structure, A three-dimensional numerical model was developed to analyze the effect of the residual stresses induced in the fiber and in the matrix during cooling from the elaboration temperature at room temperature on the behavior out of the composite. Added to commissioning constraints, these internal stresses can lead to interfacial decohesion (debonding) or damage the matrix. This study falls within this context and allows cracks behavioral analysis initiated in a metal matrix composite reinforced by unidirectional fibers in ceramic. To do this, a three-dimensional numerical model was analyzed by method of finite element (FEM). This analysis is made according to several parameters such as the size of the cracking defects, its propagation, its interaction with the interface, the volume fraction of the fibers (the fiber-fiber interdistance), orientation of the crack and the temperature.
