TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)

The nondestructive
characterization of advanced composites, such as
carbon-fiber reinforced polymers (cfrp), by electromagnetic means is
well established [6]-[24].  What is
needed to advance the state of the art are sophisticated inversion
algorithms that allow layup and impact damage to be determined in
localized regions, which means that the more traditional methods of
model-based inverse methods must be replaced by voxel-based methods.
Thus, one will be able to better distinguish such things as
delaminations from fiber-breakage due to impact damage, or other
parameters that
characterize the mechanical state of the cfrp structure, such as
elastic modulus and Poisson's ratio on a
voxel-by-voxel basis. This information can then be input to damage
evolution models.  We describe
two such methods, bilinear conjugate-gradients and set-theoretic
estimation.  The challenge is to extend these methods to anisotropic
materials.  We do that in this project, and will develop the
algorithms for inclusion
in our proprietary eddy-current code, \vic, during Phase II.
In addition, we continue our program of discovering and exploiting
parallelism in VIC-3D(R) to speed up the modeling and processing of
problems that involve massive data generation.

 

 

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA LaRC already owns
a copy of VIC-3D(R) which it uses for modeling forward and inverse
problems in eddy-current NDE. With the enhancements proposed in this
project, NASA LaRC will be able to extend its modeling capability to
more accurately characterize damage conditions in cfrps, as well as
run large problems much more efficiently.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
There are
35 commercial and university research institutions around the
world that own copies of VIC-3D(R) which they use for the same purposes as
NASA LaRC. They will have the same advantages with the enhanced
version of VIC-3D(R). Furthermore, aerospace companies, such as Boeing,
and SpaceX (Elon Musk),
that are developing vehicles that use advanced composites, such as
carbon-fiber reinforced polymers (cfrp) will be
able to use the enhanced version of VIC-3D(R). A more prosaic industry
that is using cfrp advanced composites in their vehicles is auto
racing, especially IndyCar. With a successful Phase II, we will be in
a better position to approach them and offer our services through VIC-3D(R) for
inspecting their cars. Composites are also being used in the
burgeoning wind-turbine industry, and, of course, in sporting
equipment, such as golf clubs and tennis rackets.
