EDUCATION

Master of Science in Mechanical Engineering (GPA 3.875/4.0) Jan 2016 – May 2018

Wichita State University, Wichita, KS

Bachelor of Technology in Mechanical Engineering (GPA 3.7/4.0) Aug 2010 – May 2014

Jawaharlal Nehru Technological University, Hyderabad, India

PROFESSIONAL EXPERIENCE

Research Associate July 2018 – Present

Wichita State University, Dr. Hamid M. Lankarani

oWorking on a research related to passive safety systems in Frontal, Side and Rear impacts using LS-DYNA and MADYMO.

oComponent and system level test validations for Airbags, Seatbelts and Child safety systems within vehicle environment using PRIMER and LS-DYNA.

oAiding undergraduate and graduate level students performing tasks related to their thesis on Design and Analysis of Composite Beams for automotive parts, Vehicle structural integrity and occupant safety using LS-DYNA and MADYMO determination of proper material model and properties.

Graduate Research and Teaching Assistant Jan 2016 – May 2018 (2.5 years)

Wichita State University, Wichita, Kansas

oFEA modeling of full vehicle automotive components like side impact beam, suspension system etc.

oPerformed component level tests, sled tests and full vehicle crash tests using MSC-Adams, LS-DYNA and MADYMO software. Worked on several projects using those tools.

oInvolved in modeling of lap belt for aircrafts and three-point belts for automotive, seat-belt routing, retractors, pretensioners and seat squash (seat compression).

oTrained in debugging huge DYNA deck files in case of negative volume problems, node shoot outs, contact penetrations, hourglass, energy abnormalities, simulation quality checks.

oPost-processing and documentation of numerical analysis results (stress analysis, load path analysis, energy plots, etc.) using Hyperworks, Matlab solver and MS-Excel.

oResponsible for reviewing and interpreting the post-processing results of LS-DYNA and MADYMO.

oVisited NIAR crash test lab and gained some knowledge about anthropomorphic test dummies (ATD’s) and their validation tests.

oAssisted graduate and undergraduate students for their projects related to vehicle crashworthiness and occupant kinematics by providing technical support with MADYMO, MSC-Adams and LS-DYNA tools.

Graduate Thesis Work

Title: Evaluation of far-side occupant injuries and their interaction with nearside occupants under FMVSS 214 Side Impact test requirements

oEvaluated the dynamic response of Toyota-Yaris FE model, positioned with FE model of EuroSID-2re dummy at driver and far-side with 3-point belt by utilizing FMVSS214 regulations.

oBody-to-body interactions did not show any significant increase on the severity of head injuries, but there was 50% increase in Head Injury Criterion (HIC) values when nearside occupant is restrained.

oObserved that there is 78% increase in thoracic trauma index and higher viscous criterion values when there are body-to-body interactions, leads to severe chest injuries for far-side occupants.

INDUSTRIAL EXPERIENCE

Graduate Apprenticeship Trainee Oct 2014 - Oct 2015 (1 year)

HMT Machine Tools, Ltd (Machine Tools Division), Hyderabad, India

oDeveloped 2D & 3D CAD models of machine components, assemblies, weldments, jigs and fixtures using AUTOCAD and SOLIDWORKS software.

oExperienced in drafting of part and assembly drawings by following GD&T as per HMT standards.

oWorked on several CNC Lathe machine & special purpose machine projects such as SMC, HB, HMC and VMC machines.

oFormulated ECR, ECO, ECN documentation with good interpretation and presented analysis results to engineering peers and management.

oResponsible to work with a team to create cost-effective designs and increased the revenue by more than 50% in 6 months.

oInvolved in preparing operations layouts and writing CNC programs for the multi-axis CNC machine tools with Automatic tool changers(ATC) for various operations such as milling, drilling, boring, etc.

oAssisted new trainees with the design tools, writing CNC codes and operating machines.

oSupported interaction with customers and suppliers for product design and validation along with the team.

oResponsible for preparing and releasing Bill of Materials (BOM) for quotes, documentation of technical aspects and prepared validation reports on machine builds.

oIndustrial exposure and knowledge of work at different sections such as Foundry, Fabrication, Designs, Sales, Small, Medium and Heavy Parts, CPC machines, CNC machines, CMM machines, Surface finishing and Assembly sections.
