OBJECTIVE: Highly motivated and experienced PhD graduate with Mechanical

Engineering background seeking a full time career opportunity, with

emphasis on Finite Element Analysis (FEA) and fracture/fatigue analysis for

mechanical structure designs.

EXPERIENCE:

The University of Cincinnati, Cincinnati, OH

01/2010 - present

Position: Post-Doc in the UC Simulation Center

. Investigate the complexities of tribology characteristics of polymer

materials and determine the key factors that affect material interfacial

(contact/friction) behaviors.

. Collaborate with the GTSC project team from Procter & Gamble to develop

and improve predictive FEA models for various capping simulations,

ensuring sealing performance and consumer satisfaction in product

packaging process.

. Explore LS-DYNA capacities and FEA mesh quality for industrial simulation

applications involving multi-level surface interactions. Compare with

ABQUS simulation results, and occasionally used Hypermesh for

preprocessing.

. Seek out analytical and operational method to reduce solution time for

large-scale FEA models, while maintaining simulation accuracy.

. Initiated friction test design of polymer materials under major

influential factors. Actively participate in test planning and onsite

test operations, and translate test data for FEA simulations.

. Operate proficiently with P&G High Performance Computing platform and

Ohio Supercomputer Center environment.

The University of Akron, Akron, OH

08/2004 - 12/2009

Position: Research Assistant in the Department of Mechanical

engineering

. Performed stress analysis on large scale FEA model of rotating medical

equipment, considering surface contact, mounting distortion and varied

service positions. Comprehensive FEA software package ABAQUS and IDEAS

were utilized.

. Evaluate critical load concentration in the complex rotating structure,

and estimate product fatigue life under various loading conditions using

FE-SAFE. Provided valuable guidelines for reliability design and

equipment sustainability evaluation.

. Theoretically developed the cohesive zone model (CZM) for application in

fracture analysis and fatigue crack propagation, considering distinctive

loading/unloading behaviors with nonlinear damage accumulation under

cyclic loading.

. Implemented the CZM theory as user material model embedded in finite

element solver package ABAQUS. Applied the material model for effective

2D/3D FE simulation of crack initiation and propagation. Used MSC/PATRAN

for preprocessing frequently.

. Performed finite element simulation of Carbon Nanotube (CNT) Arrays for

innovative dry adhesive design, using Cohesive Zone Model for distinct

friction and adhesion behaviors. Studied the effect of CNT array

formation/alignment on normal vs. tangential adhesive strengths, with

collaboration from Molecular Dynamics simulation results by fellow

researchers.

. Programmed proficiently for numerical data pre/post -processing with

FORTRAN and MATLAB, including adept implementation of ABAQUS user

subroutines.

. Practiced operations under Linux environment and Ohio Super Computer

interface for high-demanding computation.

Northwestern Polytechnical University, Xi'an, China

07/2001/-07/2004

Position: Research Assistant in the Department of Aircraft engineering

. Studied stress distribution in assemblies of several reinforced joints of

certain jet-training aircraft model and defined critical bolt locations

under different load cases.

. Generated detailed finite element modeling at critical bolt locations

using MSC/NASTRAN. Translated loading and constraints from FEA results of

global model, and performed stress analysis using homemade FEA software

AASA.

. Prepared cyclic loading inputs from empirical random loading spectrums

during the aircraft service life. Performed fatigue life analysis on the

detailed bolt models using the home-invented software FLA. Multiple cases

of cyclic loading were explored.

. Investigated theories of numerical optimization methods and implemented

into code programs with FORTRAN.
