Micro-mechanical Fatigue Failure in Cemented Total Hip Arthroplasty Investigation Using Acoustic Emission, 2002 – 2005
This
project is funded by the Whitaker Foundation.
The goal of this project research is to develop a better understanding of
the micro-mechanical failure behavior of total hip arthroplasty. An acoustic
emission based noninvasive techniques will be developed that utilize rigorous
experimental testing protocols to quantitatively measure the onset, accumulation
rate, progression history, and the locations of micro-mechanical failures in the
hip prosthesis under accelerated cyclic loading conditions in real time. Based
on these data, solution to when, how, and where micromechanical failures
initiate and develop will be investigated.
Nondestructive evaluation of spot-weld quality, 1999 - 2000
This
project was conduced by the request of MTD Products, Inc.
The objective of this project was to reduce and eventually eliminate the
destructive testing of frames in controlling the quality of the spot-weld, which
is one of the main machine processes in that facility.
The aims are to identify and establish a nondestructive evaluation system
to determine the weld quality of spots just-in-time, hence to save the frames
from costly destructive testing through adoption of a current nondestructive
evaluation technique.
Use
of the Acoustic Emission Technique to Study Cement Failure in Loaded Hip
Prostheses, 1999 – 2000
This
project was sponsored by a Faculty Research Grant of The University of Memphis.
The objective of this project is to
use the acoustic emission (AE) method to conduct a pilot study of using acoustic
emission technique to investigate feasibility of the loosening of hip
prostheses. The research efforts involved collection of real time AE signals and
their processing to locate the failure positions.
Design and optimization of a
prototype of kinestatic charge detector for megavoltage portal imaging, 1999 -
2001
This project
was sponsored by St. Jude Children’s Research Hospital.
In this work, classical electrodynamics and thermodynamics was applied as
an alternative engineering approach to model the KCD working environment, design
and optimize the prototype and the structural parameters using the current KCD
gantry systems at the University of Tennessee, Memphis and St. Jude Children’s
Research Hospital.
The effects of interface failure on the loosening of femoral
component of total hip arthroplasty, 2001 -
The
objective of this project is to establish a baseline of vibration technique in
detecting the loosening of femoral component of total hip arthroplasty.
The effects of Implant design on the fatigue performance in
real time using acoustic emission technique, 2002 –
This is
cooperative project with Smith & Nephew, Inc. The objective of this project
is to compare various AE signatures of different hip implant designs, hence, to
establish a noninvasive evaluation technique and to improve the quality of
implant products.
