Dissertation Advisor: Dr. Srikanth Vedantam and Prof. Lu Li, NUS, Singapore

The focus of this research is on a numerical study of microstructure evolution and experimental study of the mechanical properties of polycrystalline materials. We develop a multiphase field to study the effect of mobile and immobile particles on grain growth in a polycrystalline material. The driving force on the particles arises from the grain boundary curvature and the mobility of the particles is dependent on the particle size. The particle size is found to have a strong effect on the grain growth exponent. Mobile particles are found on the grain boundaries at an earlier time as compared to the immobile particles. Experimental studies of an Mg3%Al alloy showed a strong effect of grain size on the mechanical properties; particularly on the ductility and yield strength at elevated temperatures. The alloys with very small grains (in nanometer) showed higher yield strength and ductility at room temperature in comparison with coarse grain counterpart. Nevertheless, at elevated temperatures (>0.3 Tm) higher ductility and flat character of flow curves were attributed in the microcrystalline sample. The presence of second phase particles in these alloys are known to have significant effect on the microstructure and hence on the mechanical properties.

(c) Master Research: Buckling of Laminated Thick Annular Plates and Shallow Caps

Dissertation Advisor: Prof. P.C. Dumir and Prof. G.P. Dube, IIT Delhi, India

The aim of the thesis is to use orthogonal point collocation method in the space domain and the Newmark–b method in the time domain for buckling and postbuckling analysis of thick laminated annular plates and shallow spherical and conical caps. An approximate Galerkin solution for nonlinear response of symmetrically laminated plate has been presented. The compatibility equation is solved exactly to yield stress function. The static and dynamic buckling of shallow, truncated, conical and spherical laminated caps under static transverse load has been investigated using first order shear deformation theory (FSDT) and classical lamination theory (CLT). In context of some key results, it has been observed that the shear effect on the in-plane buckling load increases with the modular ratio and much greater for the clamped plates than the simply supported ones. This effect is to reduce the buckling load of shallow annular caps and the effect is increased with the thickness parameter and modular ratio.
