the brain functioning of a mouse.

Master of Science Projects:

Fracture Mechanics Project:

April

2015

Title: Analysis of a plate with cracks emanating from both sides

. The task of the project was to find the Stress Intensity Factor

(SIF) for the specimen under tensile loading.

. The results obtained from FEA were verified by the analytic

calculation which matched very closely.

Unigraphics Project:

June 2014 - July 2014

Title: Design multi-plate friction clutch using NX 8.0

. Modelled and drafted all parts of a multi-plate friction clutch.

. Created all sub-assemblies and exploded views of all sub-

assemblies.

. Created part and assembly drawings based on the 3D models.

Crash Worthiness Project:

March

2015

Title: FEM frontal crash test simulation of Chevrolet C2500 pickup

. 25 mph full barrier head-on impact - FMVSS 208 simulation

. 25 mph into 25 % offset rigid barrier impact (IIHS TEST PROTOCOL)

. Determining overall vehicle deformations at every 20 ms

. Analyzing the crash pulse, barrier force, structural deformation

fore and aft engine and comparing with available crush space, and

checking for intrusion into occupant space.

. Simulation with Hybrid III dummy 50th Male dummy at driver's

position and analyzing dummy response and injury curves.

. Suggesting measures of how to improve the car's effectiveness and

to reduce injuries for frontal crash less.

Abaqus Project:

Nov 2014

Title: Predict the fatigue life of solder balls in completely filled

clean and non-clean flip-chip packages to understand the effects of

processing issues using Hyper mesh and Abaqus.

. Predicted the fatigue life of filled and bare Chip flip chip

packages to understand the effect of under fill material.

. Created FEA mesh on Flip chip packages to investigate whether the

reliability of flip-chip solder interconnects are affected by the

manufacturing induced defects.

Durability and structural analysis project:

Nov 2014 - Dec 2014

Title: FE Modeling of Micro-Indentation with Spherical Indenter

. ABAQUS finite element program is used for implementation of the

project finite element analysis of micro indentation hardness

test.

Title: Thermal Analysis and optimization of I.C engine Piston using

Finite element Method

. The optimal mathematical model which includes deformation of

piston crown and quality of piston and piston skirt.

. In this project, mesh is applied to the whole structure and FEA

analysis is carried out.

. Components created - Piston

. Software - Hyper mesh

. Simulation Software- Optistruct

Automotive Manufacturing Project:

May 2014 - July 2014

Title: Study content of materials used in automotive applications

. In this project, content of different traditional and modern

materials were discussed.

. Current trend of automotive to replace some steel components with

currently available low cost and light-weight materials which

results in lower part weight, higher fuel efficiency, low emission

and low cost with meeting strength requirements.

. Vehicle weight reduction is a known strategy to address growing

concerns about greenhouse gas emissions and fuel use by passenger

vehicles. This project was limited on the available manufacturing

data.

Sustainability Manufacturing Project:

Oct 2014 - Dec 2014

Title: LCIA of the cathodes in Lithium-ion Batteries using OPEN LCA

. In this project, the influence of variation of product modularity

on the environmental sustainability is determined using OPEN LCA.

. Open LCA is an open source software which is used for professional

life cycle modelling, up to date usability, Life Cycle Costing

(LCC) Environment Product Declaration (EPD) and Life Cycle

Assessment.

Bachelor of Science Projects:

June 2012 - Oct 2012

Title: Solid modeling and Manufacturing of a connecting Rod by using

PRO/E, Catia-V5

. The project work "Solid modeling and manufacturing" deals with 3-

Dimensional modeling and detailed manufacturing process of a

connecting rod.

. By using pro/e, the modeling time spent on producing the complex

3d model and the risks to be taken in imagination of the

manufacturing process can be totally eliminated.

. By manufacturing the connecting rod using CNC manufacturing

system, it takes care of all factors such as accuracy, surface

finish and the time consumed in manufacturing the final Product,

thus making the overall operation easy to use and flexible. Hence,

I have chosen pro/e for solid modeling and the CNC system for

manufacturing.

Bachelor of Science: Final Year Project

Oct 2012 - March2013 Title:

Production of Seamless Rocket Motor Tube suing Reverse Flow Forming

. The aim of this work is to study the effect of various parameters

like roller radius, stagger, and hardness and feed on the final

flow formed tube dimensions at different reduction rates on flow

forming process of rocket motor tube for pressure vessel

application in aerospace engineering and missile technology.

. This work is carried out on the "PRODUCTION OF SEAMLESS ROCKET

MOTOR TUBE" on flow forming machine. Rocket motor tube is used as

a pressure vessel in various missiles. It encases propellant and

plays a vital role in missile thrust technology. The material

chosen for study is SAE 4130 Steel.

. The ovality of the tubes, mean diameter, surface finish and

thickness variation were also studied. Flow forming offers you the

unique possibility of forming to size a pre-hardened work piece,

thus eliminating the difficulties and high costs associated with

final machining, grinding and honing of a hardened and distorted

hollow component.
