Welcome to the Advanced Manufacturing Laboratory
we focus on the scientific investigation of
advanced manufacturing processes to improve
quality and productivity in industry, as well as
advanced robotic techniques for industrial and
health care applications. Much of our work
accomplishes this via laser technologies.
Laser Forming of
Sandwich Panels with Metal Foam Cores,
(2018)T. Bucher, S. Cardenas, R. Werma, W.
Li, Y.L. Yao.
allows bending metal foam sandwich panels up
to large angles without reducing the
shock-absorption capacity of the foam core
or delaminating the metallic facesheets.
This technology opens up many potential
applications in the aerospace, automotive,
and energy industries.
Interlaminar Toughening of GFRP—Part I: Bonding
Improvement Through Diffusion and Precipitation
(2017) D. Bian, B.R. Beeksma, D.J. Shim, M.
Jones, Y.L. Yao.
low concentrated polystyrene (PS) additive to
epoxy is used, since it is able to reduce the
curing reaction rate but not at the cost of
increasing viscosity and decreasing glass
transition temperature of the curing epoxy. The
modified epoxy is cocured with a compatible
thermoplastic interleaf during the vacuum
assisted resin transfer molding (VARTM) to
toughen the interlaminar of the composites. The
diffusion and precipitation
the most compatible polymer PSU and epoxy formed
(semi-IPN). Uniaxial tensile tests were
performed to quantify the effects of diffusion
and precipitation regions on composite
delamination resistance and toughness. Crack
paths were observed to characterize crack
propagation and arrest mechanism.
Shock Peening for Suppression of
Hydrogen-Induced Martensitic Transformation
in Stress Corrosion Cracking
(2017). G. Brandal, Y.L.Yao
Laser shock peening (LSP) improves the
resistance of a material to stress corrosion
cracking. The increased resistance is not
just attributed to compressive residual
stresses, but is also due to microstructural
changes that occur during LSP. Dislocations
created during LSP reduce the hydrogen
concentration, thereby preventing the phase
transformation from austenite to martensite.
has joined AML in September 2018 to start
his MS/PhD program in manufacturing
research. Tom received his BS in Mechanical
Engineering from Mississippi State
Prof. Yao attended
MSEC/NAMRC Conference in Texas A&M
June 18 to 21, 2018. He presented a paper
“Interlaminar Toughening of Fiber Reinforced
Polymers by Synergistic Modification of
Resin and Fiber,” which is based on
collaboration with GE Global Research and
funded by a GOALI grant from National
Science Foundation. He also hosted an
editorial board meeting of ASME Journal of
Manufacturing Science and Engineering, of
which he is the editor.
Prof. Yao was
invited to attend Editors-in-Chief Summit
of Scientific Journals sponsored by the
Chinese Association of Science and
Technology in China May 2018. He delivered
a keynote speech. Other invitees include
EICs of Science, Nature, and other leading
and Breanna Johnson started their
8-week summer research with AML late May,
2018. They were supported by Research
Experience for Undergraduates (REU) program
of National Science Foundation. Each of
them was involved in an active research
project going on in the AML.

center in Spain and served as the Dean of
Engineering at University of Vigo for six
Prof. Yao attended
the ASME Technical Committee on
Publications and Communications/Board of
Editors meeting held in Tampa, FL on
November 4-5, 2017. He currently serves as
Editor, ASME Journal of Manufacturing
Science and Engineering. He exchanged views
with editors of other ASME journals.
