Response of Erythrocytes in capillaries.

Performed Fluid Structure Interaction analysis on ANSYS 16.2 WB to find response blood cells in capillaries.

Combined Transient structural and Fluent by system coupling component to imitate solid RBC in the fluid blood stream.

Utilized Ogden hyper-elastic material in ANSYS 16.2 material library to apply on the RBC and perform FSI.

The RBC was under high stress in shear flow of blood and stagnation of blood is observed more in laminar flow of blood. Static Structural Design and Analysis of Connecting Rod with optimized mass.

Achieved in finding the design parameters for a connecting rod (conrod) under tension and compression.

The mass of rod was optimized and stress produced below prescribed Von-misses stress of 250 MPa.

St. Venants’ principle was applied in finding the stresses acting on the conrod.

Utilized ANSYS APDL for analysis and EXCEL and MATLAB for graphs. The weight of the final product obtained is 1.780 lbs. Material Selection for a Hip-implant.

The stress and deformation results in response to applied loads are recorded and found ASTM F1295 Ti-6Al- 7Nb as material for a hip prosthesis.

Several loading scenarios and underlying physiological states are considered.

The other materials considered were zirconia, zirconium alloy, titanium alloy, and molybdenum.

Utilized Solidworks for design and analysis on COMSOL software. Study on mechanical properties enhancement when T300/5208 composite is utilized on ice hockey-stick

Designed a multilayered T300/5208 composite hockey stick.

Compared stiffness, weight and responsiveness parameters to that of an Aluminum hockey stick of same dimensions.

During slap-shot, maximum deflection in the bat made from T300/5208 composite was reduced by 15.89% when compared to Aluminum bat.

Designed ice-hockey stick on Solidworks and analyzed on ANSYS APDL by applying Tsai-Wu and Tsai-Hill failure criteria. Aerodynamic characterization of Cambered plates, used as wings in micro-air vehicles.

Performed CFD analysis for different cambered plates for ultra-low Reynolds number in a wind tunnel.

it was observed that 9% cambered plates produced highest lift with least drag.

The experimental results matched were validated with the numerical solution with error percentage of 1.69%. Minimization of disc brake stopping time of passenger Vehicle.

Achieved in finding the minimum stopping time of 2.11 seconds for a disc brake utilizing design optimization techniques.
