ENGINEERING EXPERIENCE

FEA Analysis of Automotive Suspension System, Spring 2017

Preprocessing in Hypermesh: Generated finite element mesh for suspension system components(leaf spring, center bolt, cushion, supporter, bearings). Applied material properties of components, contacts between components, boundary conditions, loading steps. Exported .inp file for finite element analysis.

FEM analysis and Postprocessing in ABAQUS: Ran finite element analysis with .inp file in ABAQUS. Analyzed the results to find the most dangerous area of suspension system for fatigue analysis.

Finite Element Method Course Projects, University of Akron, Fall 2013

FEM simulation of metal plate with inner holes: used different mesh sizes and element types, studied convergence of displacement, studied effect of mesh on stress concentration around holes and corners.

FEM coding in Matlab to solve simple truss problem. Skills learned: understanding of finite element theory.

ABAQUS UMAT subroutine programming of user-defined stress-strain relationship for FEM analysis of cantilever beam in ABAQUS. Skills learned: simple ABAQUS secondary development

Linear and non-linear FEM dynamic simulation by ABAQUS and SAP2000: 1) progressive failure study of 2D frame under cyclic loading. 2) response of a planar over-pass bridge girder under moving-loading.

Research Assistant, University of Akron, Akron, Ohio, Sep. 2013-May 2016

Stochastic discrete damage analyses of laminate composites

Description: Generate 3D finite element model of laminate layer in Hypermesh. Scripted in Matlab to model randomness of strength(Yt and S) with 2-D Gaussian random fields. Performed Monte Carlo based FEM damage analysis of carbon/epoxy laminate composite by BSAM (FEA software by NASA). Studied damage pattern (delamination, matrix cracking) and parameter sensitivity. Published a technical paper.

Teaching Assistant, Department of Civil Engineering, University of Akron, Sep. 2013-May 2016
