EXPERIENCE

Larsen & Toubro Ltd. – Heavy Engineering, Mumbai, India Jul 2010 – Jul 2012

Executive Engineer I, Department: Technology Development Center (Mar 2011 – Jul 2012)

Researched, developed and validated the technology to simulate the welding process in order to determine the

distortion and residual stresses generated during welding, using ABAQUS and Python.

o Created an interface that allows user inputs for size, shape of weld, no: of passes, heat input and mesh.

o Validated the simulation with results obtained from a physical experimental weld.

Conducted design, failure, structural and thermal analyses of equipment using ANSYS, ABAQUS FEA (implicit,

explicit, nonlinear, static, dynamic) tools and AutoCAD, Unigraphics, and other design tools.

o Resolved distortion problems in exhaust neck design of condenser units in power plants using ANSYS.

o Analyzed local stress relieving heat treatment procedure carried out on a heat exchanger.

Provided detailed analytical and design support to other business units within the company.

Executive Engineer I, Department: Quality Control (Jul 2010 – Mar 2011)

Ensured the quality standards of parts manufactured on the shop floor as per design standards like ASME, IBR, etc.

Conducted inspection operations utilizing various testing instruments.

Handled material inspection & inventory verification through BaaN ERP tool and documentation through PLM tool.

PROJECTS

Title: Finite Element Analysis – Validation via Implementation Fall 2013

Performed two structural analysis using ABAQUS on a thin wall and a pipe-shell assembly.

Proved understanding of the finite element method of analysis by implementing the same in Matlab, repeating the

analyses and comparing the results obtained, with those from ABAQUS.

Title: Material Selection for a Tennis Racquet Frame Fall 2013

Translated the design requirements of the racquet frame into constraints, objectives and variables.

Screened an initial pool of materials using the variables, constraints and ranked the materials as per the objectives.

Investigated the final material set to determine the best possible material for the racquet frame.

Title: Design of Automobile Interactive Diagnostic System Spring 2013

Developed and demonstrated as a team, a prototype system on Eclipse software that predicts possible internal dangers

while driving an automobile, warns the user before occurrence and, in case of damage, enables user to call for help.

Designed the system and its object class diagram following Object Modeling Techniques (OMT).

Title: Failure Analysis of a Melamine Bowl Spring 2013

Analyzed the reason for the formation of a fracture zone and subsequent rupture in a melamine bowl.

Conducted macroscopic fracture surface examination of the area of fracture.

Catalogued the observations and inferences and reviewed them to determine the type and method of fracture.

Title: Design of a CAD controller that reduces RSI (Repeated Stress Injuries) Fall 2012

Conceptualized a Computer Aided Design (CAD) Controller in SolidWorks, to be used by CAD engineers, using a

structured method of design called innovative design thinking (IDT).

Transformed functional requirements of design into design parameters to enable best form of conceptualization.

Utilized TRIZ techniques to improve upon the initial concept and obtain the final end product.
