OBJECTIVE

Seeking a Research & Development opportunity that utilizes my technical skills and educational background to influence organizational growth & bottom line profitability

SUMMARY

* Experienced professional with over 10 years of experience in experimental characterization of polymeric/elastomeric & composite materials, mechanical design, test method development, finite element analysis & modeling, and mechatronics.

* Extensive experience in adhesion mechanics, fracture-based testing of polymers & composite testing, failure analysis, environmental and chemical resistance, accelerated testing, physical aging, rubber processing & extrusion, and rubber compounding.

PROFESSIONAL EXPERIENCE

COOPER TIRE & RUBBER COMPANY, FINDLAY, OH

Materials Development Engineer, Material Development Department OCTOBER, 2012 – CURRENT

* Tread compound development for Ultra High Performance (UHP) and Off-road tire lines with emphasis on improving rolling resistance (RR), wet traction, wear and handling characteristics

* Determined compounding variables related to tread formulations which significantly affected tire performance

Research Engineer, Research & Technology Department MAY, 2009 – OCTOBER, 2012

* Design & development of fixtures, test methods, procedures to perform thermo-mechanical characterization of cord-rubber composites used in tires. Developed Digital Imaging procedure (including calibration) on a Digital Image Correlation (DIC) system to acquire 3D strain distribution data from the sample during testing. Development of test method on an Instron Servohydraulic load frame to conduct experiments on composite laminates to generate material stiffness coefficients to help understand the stress-strain behavior of plies/belts. Validated the experimental results with theoretical predictions based on the Classical Lamination Theory (CLT).

* Finite element characterization of the effect of cord construction parameters (EPI, twist, lay length etc.) on hysteretic losses in steel cord-rubber composite belts in tires using ABAQUS

* Quasi-static & dynamic characterization of adhesion strength between cord & rubber using " pull through and TCAT tests. Developed simulation of failure at cord-rubber interface utilizing cohesive zone modeling (CZM) approach in ABAQUS.

* Development of an experimental approach to study the effect of processing parameters on textile cord’s viscoelastic/mechanical behavior in terms of elastic & thermal shrinkage properties, viscoelastic creep/stress relaxation and viscoelastic dissipation for use in tire FE modeling

* Development of a mathematical Predictive Modeling tool using the commercial code MATHEMATICA® to help design belt package for tires and estimate its stiffness in circumferential, meridional & out-of-plane bending directions to help predict ride harshness, tread wear & plysteer behavior.

* Design & development of a real-time LabVIEW based gas permeation system to help estimate compound permeability under various test conditions. This automated multi-chamber design reduced the testing time by 80% which was achieved via instrumentation and LabVIEW programming for data acquisition, control & test analysis. Also designed a real time predictive modeling module in LabVIEW based on Arrhenius approach.

* Study the effect of raw material and mixed stock variation on tread extrusion consistency by:

1.Developing test methods & procedures to prepare samples and conduct testing on a GOETTFERT capillary rheometer to study the effect of variation in incoming raw materials (carbon black, silica, natural rubber, styrene butadiene rubber, accelerators etc.) used in tire compounds and process parameters (mixing cycle, temperature, shear rate etc.) on extrudate variation in terms of die swell, porosity, green strength, cured strength etc.

2.Using CAE tools HyperMesh & HyperXtrude for simulating the extrusion process through dies using CAD imported die profile and dimensions, material properties (such as green rubber modulus, thermal conductivity & die swell behavior) obtained from testing on capillary rheometer. Virtual testing, validation, correction and optimization of extrusion process were carried out using HyperXtrude.

* Developed a custom designed pressurized equibiaxial test using LabVIEW & DIC for material characterization to support Computer Aided Engineering (CAE) efforts to develop improved tire models in ABAQUS.

* Mentored co-ops & interns on various projects.
