Graduate Research Assistant Resume Example

• Instructed three classes of 50 students each in the semester and received feedback from students and professors.
• Conducted office hours to help the students visualize a loading condition and applicability of the theory in practice.
• Designed and solved homework problems, quizzes and exams.

• Conducted Thermo Mechanical Fatigue simulations on notched specimens using Garofalo creep and temperature dependent multilinear isotropic hardening plastic material models.
• Validated the results with data obtained from laboratory experiments.
• Evaluated the effects of notch radius, temperature range, applied load and phase on thermo mechanical fatigue life.
• Analysed the simulations statistically and obtained coefficients to extend the model to predict component level failure.

• Demonstrated several sections of term project on asperity interaction and evaluation of contact stresses.
• Explained challenging problems in elasticity to a graduate class of 80 (50 off campus) students.
• Evaluated homework, projects, exams and held office hours to discuss concepts with the students.

Material Testing and Selection:

• Characterized materials (AISI 1045, 4140, 6150, 1070, ADI) and surface engineering techniques (Case hardening, nitriding, cryogenization, carburizing, hard chrome, TiAl coating) for fatigue and wear resistance and provided material expertise to designers
• Initiated abrasive wear research by developing ASTM G65 based test stand and evaluated wear rates of steel and aluminum alloys
• Designed and developed a customized test stand to simulate actual harvester operating conditions and conducted experiments on selected designs and materials to measure sliding wear

Product Design and Analysis:

• Product Life Cycle - Recommended design modifications based on failure analysis for components conceptualized for model year 2017 agricultural machinery.
• Worked with the mule build team to design components (Aluminum Extrusions) with maximum strength to weight ratio. Identified critical parameters: Manufacturability (DFM), Cost Analysis, Material Selection, Fatigue Strength etc.
• Conducted Root Cause Analysis (RCA) and Failure Mode and Effects Analysis (FMEA) to identify failure parameters on old design and recommended necessary changes in the new design
