Master's Thesis: ¡* Multi-scale analysis of the effect of cavitation on the stability and failure during Superplastic deformation¡¨. This involved developing a stability criterion for analysis of failure and stability during Superplastic deformation, by using a modified constitutive equation coupled with micro-structural evolution equations. It mainly focuses on studying the effect of cavitation on stable deformation of superplastic alloys. I have also extended the model to account for nucleation of cavities, different loading conditions and anisotropy. Another aspect of my research is to experimentally evaluate the mechanical properties and also investigate micro-structural aspects like grain growth and cavitation, in superplastic materials.
Projects:
i. Analysis on the transformation superplasticity in metals and ceramics.
ii. Experimental investigation on the mechanical properties of brazed structures using INSTRON.
iii. An investigation on the manufacturing and mechanical properties of Metallic foams.
iv. Experimental investigation on the thermo-mechanical properties of Al-3004.
v. Comparison of 2D and 3D models of sheet metal forming using LS-Dyna.
vi. Finite Element Simulation of sheet metal forming to analyze the effect of material parameters.
vii. Experimental investigation on the effect of guide vanes for optimizing the performance of an axial flow fan.
