In this paper, investigated the effect of Al 6061 T6 solid specimen dimensions on torsional tests on yield shear stress. Torsion experiments were conducted at various levels of solid aluminum samples using key sample dimensions such as outer diameter, effective length, total length and fillet radius. Taguchi parameter design and optimization approaches are used to design experiments, and then predict the optimal set of parameters. Multi-objective optimization was done using the Grey Relational Analysis (GRA) method. In the GRA method, a grey relational grade is found to determine a set of parameters for multi-objective optimization of parameters. It is found that the outer diameter has a greater effect on the yield shear stress.
