A plastic deformation analysis of unidirectional continuous fiber-reinforced metal matrix composite (MMC) systems is carried out using the finite element method. Two patterns of fiber arrangement, square and close packed patterns, are examined using a two-phase rigid-plastic finite element analysis method and assuming plane strain conditions. Different combinations of friction and number of fibers are tested and the resulting deformation patterns and required flow stresses are recorded. Based on the saturated flow stress values and similar final profiles as the number of fibers in the systems increases, equivalent material models are proposed to simplify the design procedure for forging the pre-consolidated MMC systems.
