Fast full-wave analysis of damaged periodic fiber-reinforced laminates
Abstract
A computationally efficient modeling approach to
analyze TM and TE electromagnetic scattering from periodic
fiber-reinforced laminates is introduced, when they suffer from
missing, shrunk/expanded, displaced fibers, and inclusions. Such
damages inside the initially periodic structure (the fibers as
organized in a given matrix) are seen as undamaged zones
with fictitious line sources properly set inside them, and the
field results as a summation of responses to the exterior source
and equivalent ones. Then, methods for periodic structures can
readily be used. Various numerical results are proposed that are
evidencing the interest of this approach.
