Assistant
Professor
Dr.
Lingyu
Yu’s
research
interests
include
structural
health
monitoring (SHM)
and
nondestructive
evaluation (NDE)
using
ultrasonic
guided waves
supported by
active
sensor
technology,
theoretical
modeling,
advanced
signal
processing
and data
analysis;
damage
diagnosis in
complicated
structures;
scanning
laser
vibrometry
for guided
wave
propagation;
and
mechatronics.
Current
research
efforts
include
developing a
multi-scale
damage
detection
approach on
composite
structures,
developing
imaging
strategies
for
permanently
installed
SHM
system to
perform
in-situ
damage
detection,
and
exploiting
advances
made in
other areas
to introduce
innovative
methods into
SHM/NDE.
Applications
of this type
of research
include
condition
monitoring
of the
aircraft
structures
and systems,
integrity
monitoring
of large
composite
structures,
detecting
and
quantifying
cracks in
metal
structures
such as
steel
bridges and
their
subsequent
propagation,
corrosion
growth
monitoring
in piping
structures,
and many
more.
