摘要

The present study introduces a novel 2-D axisymmetric FE methodology to simulate cold forging behavior for aluminum metal matrix composite materials reinforced with short carbon fibers, which are found to be insufficiently characterized in terms of their forging behavior in existing literature. Unlike existing cold forging analyses for monolithic aluminum alloys or aluminum metal matrix composite materials, this study addresses intricate spline groove formations in the radial direction of composite materials by incorporating elastoplastic materials and a sliding-stacking friction model to simulate die-workpiece interaction during cold forging. An experimentally validated ANSYS APDL FE simulation methodology was implemented to ensure accurate prediction of cold forging behavior for aluminum metal matrix composite materials reinforced with short carbon fibers. Parametric analyses of cold forging behavior for aluminum metal matrix composite materials reinforced with short carbon fibers reveal that axial feed rate per stroke and friction coefficient significantly influence the generation of compressive residual stresses and forging loads required for cold forging of aluminum metal matrix composite materials reinforced with short carbon fibers, which are found to be 200 MPa in magnitude on both die surfaces, with maximum forging pressures of 350 MPa and maximum forging loads of 6.4 MN at a friction coefficient of 0.16.
