dc.description.abstract <p>The weight reduction of a structure is of utmost importance for the aerospace applications. One of the efficient ways to reduce the weight is the use of heterogeneous materials. A heterogeneous material is one that is composed of two or more different materials in a certain proportion. The rapid prototyping processes have made it possible to fabricate a single structure by the deposition of different materials at different locations, hence, allowing the material properties to be controlled in the desired manner throughout the structure. In this work, aluminum and titanium have been used to minimize the weight of a typical axial compressor rotor blade. The focus is on optimizing the volume fractions of Al-Ti throughout the structure, in the presence of certain constraints. Three cases are presented, two of them are for the plate where once the material is allowed to vary just in one direction and second where the material is allowed to vary along all three directions and the third one is that of the compressor rotor blade itself. The results from the sample plate case give a good insight into the desired material distribution, in the light of which the optimization for the blade has been performed to minimize the weight.</p>
