WORK

HISTORY

GRADUATE RESEARCH ASSISTANT 09/2013 to CURRENT

University Of New Hampshire Durham, NH

• Characterized material properties of automotive aluminum and commercial titanium alloys for anisotropic plasticity, damage, and fracture criteria using conventional and novel experimental techniques.

• Operated and programmed servo-hydraulic test frames, pressure systems and high- temperature furnace for mechanical testing of materials and data acquisition from displacement, load, pressure and temperature sensors.

• Implemented Digital Image Correlation (DIC) and Infra-Red Imaging techniques to capture full strain and temperature fields during deformation.

• Performed experimental characterization and constitutive modeling of Tantalum single crystal subjected to simple compression.

• Calibrated advanced anisotropic yield functions (Hill48, Yld2000-2D, Yld2004-3D, CPB06, KYL) for implementation in finite element analysis (FEA).

• Performed finite element simulations of non-linear material behaviors using ABAQUS after implementing advanced constitutive modeling with user-material subroutines to predict fracture behavior of metals.

• Conducted plasticity and ductile fracture modeling of several aluminum alloys

(casting: Aural2-T7, Aural5S-T5, extrusion: HS6X-T6, RX82-T6, sheet: AA6013-T4, AA6022-T4, AA6111-T4) using experiments and numerical analyses.

• Designed, proposed and implemented novel specimens and experiments for ductile fracture characterization.

• Contributed to ductile fracture literature by proposing and publishing a new fracture initiation model in an international journal.

• Planned, modified and executed fracture modeling of extruded tubes loaded under internal pressure and axial force for hydroforming applications.

• Designed acoustic emission (AE) sensor using piezo-crystals and implemented signal processing and analysis techniques to detect localized necking and fracture of metals in forming processes.

• Prepared materials for reports, presentations and submission to peer-reviewed journal publications.

• Supervised undergraduate students working on research projects. UNDERGRADUATE RESEARCH ASSISTANT 09/2011 to 12/2012 Idaho State University Pocatello, ID

• Characterized, processed and analyzed surface electromyography (sEMG) signals for implementation in the development and control of smart prosthetic Hand.

• Studied the effects of air moving past solid objects in a wind tunnel.

• Measured and analyzed subcriticality and rod worth of an AGN-201 nuclear research reactor.

INTERN 05/2011 to 08/2011

Engineering Research Complex Pocatello, ID
