Research Experience

Present Graduate Research Assistant, Center for Tire Research (CenTiRe), Virginia Tech, Blacksburg, Virginia

• Working on two projects viz ‘Comprehensive Multiscale Modelling of Tire Wear’ & ‘Rubber Lifetime Performance: Coupling Effects Dynamic Aging and Wear’

• Performed experimental tests on a ‘Dynamic Friction Tester’ (DFT) to characterize wear and to study the effects of thermal (chemical) and mechanical aging on the tire wear and life.

• Performed SEM imaging to study wear pattern at different test conditions. Aim to couple the aging and wear damage function with the mechanical responses of rubber in the context of the CDM theory and develop p a finite element model.

• Creation of a UMAT subroutine after creation of a mathematical model to define the material properties in ABAQUS. 2018-19 Undergraduate researcher, Experimental Investigation and Simulation of TiAl6V4 with PVD Coated inserts, NMIMS University, Mumbai, India.

• Used TiAlN and AlCrN alloy coatings on low grade carbide inserts using magnetron sputtering technique to machine TiAl6V4 titanium alloy to reduce tool wear during machining and simultaneously increase tool life and performance.

• Conducted testing on a CNC lathe and input parameters such as speed, feed, and depth of cut were varied to find the optimum output parameters viz. low cutting forces, low surface roughness and less tool wear

• Demonstrated the reduction in lead time, tool changeover time and simultaneous increase in tool life, quality & efficiency

• Performed simulations on Deform 3D software to validate the results. Focsus was to improve quality and cut down costs.

Technical/Work Experience

May-Sep ‘18 Mechanical Design Intern, Nuclear Power Corporation of India Ltd, Mumbai, India

(5 months) • Worked in the Design Department wherein was assigned to develop CAD models of pressure vessels and correct any aberrations. Analyzed various components for different types of failures on ANSYS and consulted on improvements.

• Studied the stresses induced in pressure vessels of various geometries & the design requirement to combat them

• Performed analytical calculations to calculate discontinuity stress in the head-shell junction of a pressure vessel used by NPCIL using ASME Section III Division-1-NC. Prepared a code and report on the same and gave a technical presentation. 2017-2018 ATV Design and Manufacturing, MPSTME Racing Team, SAE Baja India & Enduro Student India (ESI)

(9 months) • Headed the Manufacturing department of the MPSTME Racing Team and worked in the design department to model and analyze the chassis for various failure modes. Performed failure analysis on knuckle-spindle assembly.

• Assisted in suspension designing and manufacturing to ensure better ride and handling characteristics.

• Aimed to reduce the weight of the chassis while considering ergonomics as well as rigidity of the structure A change in material selection and innovative design changes made the vehicle about 15% lighter than its predecessor.
