Advanced composite materials are replacing conventional metals/alloys in aerospace industries due to their excellent strength and stiffness-to-density ratio as well as some other better physical and mechanical properties ...

The thesis deals with the aerodynamic analysis of a nose-mounted propeller aircraft using the flow solver HiFUN. Unsteady RANS simulations using sliding mesh technology is performed on aircraft with the propeller. The study ...

This thesis revisits the design of a planar supersonic nozzle for a supersonic wind tunnel using the method of characteristics (MOC) and Computational Fluid Dynamics (CFD). While design of a converging-diverging (CD) ...

Structural ceramics such as alumina are known to have excellent hardness and high temperature mechanical properties. In view of this, they are used as refractory linings to mitigate the effect of high temperature exposure. ...

Graphene oxide (GO) is a chemically functionalized graphene with various oxygen-containing functional groups, such as epoxy (-O-), hydroxyl (-OH), and carboxyl (-COOH) on the basal plane. As a consequence, GOs have hydrophilic ...

Commercially pure Cu was processed through high-pressure torsion (HPT) at a pressure of 6 GPa starting from ¼ up to 50 turns. These samples were then naturally aged for 1.75 years under the laboratory condition. Subsequently, ...

Cemented granular systems are encountered at various scales in nature and artificially. We present an experimental study carried out on the structure and mechanical behaviour of weakly cemented granular materials. We study ...

Shape memory alloys (SMA) are those class of alloys that can cause shape memory, pseudoelastcity and two-way memory effects due to reversible austenite to martensite phase transformations. The NiTi shape memory alloys ...

Ti-Nb-Ta-Zr based β-Titanium alloys are currently projected as potential candidates for use in orthopaedic implants owing to their low elastic modulus and use of non-toxic elements. However, most of these alloys contain ...

In conventional Finite Element Method (FEM), triangular and quadrilateral elements are commonly used finite elements and their counterparts with tetrahedral and hexahedral elements in three-dimensions to discretize the ...
