EXPERIENCE
Research Assistant, Advanced Metal Forming & Tribology Lab, NCSU August 2007 – Current
 Temperature Prediction in Ultrasonic Microextrusion Process
 Designed and fabricated 2nd generation ultrasonic microforming test set-up. Conducted stress
analysis for the structure. This set-up is currently used for microextrusion where the ultrasonic energy
is applied to enhance that process.
 Performed numerical modal and harmonic response analyses (ANSYS) to quantify the ultrasonic
wave propagation.
 Measured the amplitudes of the ultrasonic energy at different locations of the test set-up using Laser
Vibrometer, strain gauge and NI SCXI DAQ with LabVIEW programming.
 Characterized different brass materials to be used for the microextrusion tests.
 Developed a finite element analysis code using FORTRAN to analyze the deformation of the surface
roughness asperities based on elasto-plastic solid mechanics during the microextrusion process.
 Performed numerical transient thermal analysis (ANSYS) to predict the temperature rise.
 Produced micro-parts by the ultrasonic energy (20 kHz) assisted extrusion process.

2.  Real-Time Loading Path for Tube Hydroforming (THF) Process
 Developed an analytical model based on solid mechanics to generate the pressure curves for THF
process. Analyzed the failure criterion for the THF process.
 Built a database using numerical simulation (Abaqus-Explicit) consisting loading paths for 189
unique sets of THF parameters.
 Produced real-time loading path for THF process from the database by multidimensional cubic spline
interpolation using MATLAB programming.
 Designed and fabricated two sets of THF (Double-T and Double-Y) dies to produce THF parts.
 Tribo Test for Lubricants used in Metal Forming
 Generated the friction calibration curves for the ring compression and double cup extrusion tests
using finite element analysis (DEFORM2D).
 Conducted ring compression and ball penetration tests to evaluate different commercial lubricants.
 Press Forming
 Designed and fabricated a support frame for the bottom structure of a 150 ton hydraulic press to
prevent the failure of the hardened dies due to fracture.
 Upsetting Process
 Analyzed an upsetting of folded sheet metal using finite element method (DEFORM2D) to obtain the
forming load and die stress analysis information required for commercial process design.
