Abdulmawlla, Mohamed A. PhD thesis, Universiti Putra Malaysia. The demand for lighter and stiffer products has been increasing in the last few years especially in automobile and aerospace manufacturing.
The closed die forging process of aluminium metal matrix composite Al-MMC material is presented as possible solution, because it produces parts with good mechanical properties and lighter weight.
In this work, a commercial finite element software, ANSYS has been used to model cold closed die forging process. The model is developed using ANSYS ParametricDesign Language APDL to simulate a single stage axi-symmetry closed die forging process for H-cross sectional shape. So that the H-cross sectional shape used in this study has a wide applications. Simple compression test was carried out for aluminium alloy in order to determine its flow curve.
Closed die forging phd thesis on metal matrix composites was conducted using aluminium alloy and then the experiment was simulated in order to verify the model for large deformation. The simulation results showed similar output with the experimental one. As a result, the model can be confidently used to simulate closed die forging for particulate reinforced Al-MMC, phd thesis on metal matrix composites.
ANSYS Optimizer is used to obtain the maximum height that the material can flow in the rib by changing the design variables DV and the state variables SV. Generally, design variables are geometrical parameters such as rib height to width ratio, phd thesis on metal matrix composites, web height to rib height ratio, fillet radii, draft angle and billet radius.
State variables SV are some parameters that depend on the design variables such as the equivalent strain which must be below the fracture strain of the aluminium metal composite AMC material, and an acceptable contact gap within the allowable tolerance range.
The objective of this work is to achieve through simulation, the optimal die shape and billet diameter in consideration of complete die filling and the influence of metal flow deformation of Aluminium Metal Matrix Composite in a single stage closed die forging process.
A commercially available finite element package ANSYS was used to investigate the effect of different die shapes and billet diameters on the closed die forging deformation. Trying to get higher rib height lead to higher strain and cracks will occur in the fillet region. The rib width and the web height are 0. Optimal billet height is 0.
The billet radius is a function of the die cavity volume and the billet height. The technique used in this work can be used for newly developed materials to investigate its forgeability for more complicated shapes in closed die forging process.
