I was working for undergrad project ‘Six Sigma in manufacturing process’. Six sigma is the most powerful statistical tool for controlling quality of products and it provides specific methods to re-create the process itself so those defects are never produced in the first place. Six sigma tools have been studied and implemented in one of the critical manufacturing process of the turbine casing in BHEL Hyderabad, India.

Linear and nonlinear (geometric, material and contact) analysis, Modal analysis, Frequency response analysis of automotive parts, heavy engineering structures and impact analysis of different products. Also carried out topology optimization of parts. I have been using Hypermesh and Hyperview for pre and post processing; Abaqus, Nastran and Hyperworks Radioss solver for solving.

Worked on masters’ project ‘Linear and Nonlinear Analysis of Composite & Sandwich Plates subjected to Static and Dynamic Loads using Finite Element Method Formulation’. Static linear and nonlinear, modal analysis, transient, dynamic linear and nonlinear FEA code was developed in Fortran to carryout analysis of composite laminates. Also, crack arrest techniques in engineering structures, dynamic crack principles and importance of life prediction were studied as a part of ‘Fracture Mechanics’ course project. During this time as a teaching assistant, I was preparing and evaluating assignments for undergrad courses.

Designing of Jigs, Fixtures, Special purpose machines and Special Gauges using CAD tools such as Auto CAD and Solidworks. I was going through different machines and their capabilities for machining automotive diesel fuel supply system parts such as filters, pumps and injectors. Then I was designing the tools to suit for a particular machining process. Such tools are used for continuous production, where loading and unloading of the component by operator is important. These tools play important role in determining the machining time of a component.

Worked for ‘Aeronautical Research & Development Board, India’ project ‘Analysis of Composite Structures using FEM & Meshless Methods’. Matlab program was developed to carryout static and dynamic analysis of composite laminates based on meshless method & FEM. Adaptive strategy in meshless method for plate analysis are implemented and also nonlinearity is accounted for composite structures analysis.

I was responsible for Design & Development of Heavy Duty Mercedes Benz (Bharat Benz) Truck Engine parts. Also responsible for the mechanical failure and performance failure analysis of whole engine & its components during development stage and on road testing of the vehicle.
