Experimental Upset Study on Barreling Behaviour of A356 Varying Reinforced with Graphite and Granite Dust Composities

“An investigation has been performed into the effect of upset forging on commercially available A356, reinforced with Graphite and Granite dust in dry condition. The axi-symmetric specimens of cylindrical with aspect ratios 1.0 and 1.5 have been taken for the present work. The upset tests were performed at room temperature between two flat plates on a Fatigue testing machine (INSTRON Model: 8801). Experiments were carried out to generate data on the cold upset forging of solid cylinders for predicting the deformation to fracture. Due to practical difficulties in observing the crack initiation, the maximum deformation is limited to 50%. For A356 alloy and Composites, no cracks were observed. The effect of Flow stress and Flow strain with stresses namely; the Hydrostatic stress, axial stress and Circumferential of the analytical calculations were found to be in good agreement with the experimental calculations, with decrease in aspect ratio, the circumferential stress component increased monotonically”.
