Experience

CAE Engineer at Tata Technologies, Troy MI September 2016 – April 2017

Meshing of automotive castings, sheet metal parts and trim components within 5% of the prescribed quality parameters using Hypermesh

Dynamic, NVH & stress analysis and post processing of components using Abaqus 6.14

Liaison between offshore teams and local customers

Review of vehicle systems (BIW, etc.) and safety regulations (FMVSS, NCAP) in order to apply load cases for the analysis

Review regulation to identify requirements for the new design proposals

CAE Intern at Tata Motors, on deputation from Tata Technologies June 2015 – July 2015

Modal & contact analysis of a Radiator Mounting Bracket

An orphan mesh was used as input. Abaqus/CAE & Standard 6.14 was used for the analysis

Modal Analysis was performed and recommendations were made to increase the first mode frequency from the obtained 12Hz to more than 20Hz as required

Non-linear (contact) analysis considering static loading conditions as a preliminary check was performed

Validation of Analysis

Performed previously completed static and dynamic analysis and verified their correctness.

Gatorloop – SpaceX Hyperloop Pod Competition January 2016 – April 2016

Worked in a sub team responsible for the Levitation, Braking, Stability and Propulsion in the full scale modelling of the pod

Designed a mechanical system for lateral and vertical stability of the pod travelling at high speed

Contributed to the generation of an DFMEA for the pod to understand failure modes, assess its risks and carry out corrective actions

A weight reduction of 20% was achieved by combining the lateral and vertical stability systems into one module

Graduate Research Assistant – University of Florida September 2015 – December 2015

Modelling and Evaluating a Composite weave

Modelled a Representative Volume Element (RVE) containing a Fiber and a Matrix for a plain weave textile

Equivalent properties were evaluated using Abaqus 6.14

A parameterized python script was written and used as input to evaluate the properties

Academic Research & Projects

University of Florida

Topology & Sizing Design Optimization of a Beam

Topology Optimization was run for a rectangular beam using the 99-line code for required loading and boundary conditions. The optimized topology was then interpreted and modelled into a finite element model using beam elements. Size Optimization was then carried out using MATLAB with the objective of minimizing weight of the structure given axial stress constraints. A weight reduction of 162% was achieved from the initially interpreted geometry

Torque Arm Modelling, Analysis and Optimization

Modelled a Torque arm in Abaqus 6.14. The effect of varying element type and size was observed in the output. A convergence study was carried out using the Q4 element and the actual displacement of a node was predicted using Richardson’s extrapolation. The design was parameterized and selected geometric parameters were optimized to minimize the weight. A weight reduction of 1% was achieved

Finite Element Analysis & Optimization of a Plane Truss

Analysis was performed to identify the maximum nodal displacements and member stresses for 6 bay and 8 bay truss. Truss was approximated as a beam and its equivalent properties were calculated. Fully Stressed Design was used to optimize individual member c/s areas. MATLAB was interfaced with Abaqus to complete four design iterations using analytical formulae. A weight reduction of 57.87% was achieved for the truss

Fatigue Analysis of a Coke Drum and an Aircraft Fuse Pin

Root cause analysis was performed for the failure of a coke drum subjected to extreme heat and cold shocks in petroleum refineries. Investigated the crash of a Boeing 747 due to a fatigue failure of a fuse pin in the wing pylon. Estimated fatigue life using the Strain-life approach

Validation of Paper Helicopter models

Mathematical models with linear and quadratic relationship between drag and speed were to be validated. Experiments were performed using three helicopters of different masses. One helicopter was used to calibrate the coefficient of drag using Bayesian analysis while the other two were used for predictive validation. The Kolmogrov – Smirnov and Area validation metrics were used to compare the uncertainties. The linear model was validated

3D Modelling of an Electric Guitar

An electric guitar was modelled in SolidWorks. Free form elements were used to generate the body
