ALTERNATIVE THEORETICAL FRAMEWORKS FOR HYBRID SANDWICH PANEL WITH INTERMEDIATE LAYER
ABSTRACT: A concept of hybrid
sandwich panel with intermediate layer
has been introduced previously that capable of improving load
carrying capacity of
composite sandwich panel.
While the previous
work employed numerical and
experimental investigation, the
current paper more
focuses on developing
the theoretical frameworks of
the hybrid sandwich
panel by using
analytical model. The
vocal point of
the concept is introducing a
new layer in
between the skin
and the core
of a standard
sandwich panel structure
to form a hybrid structure. The paper begins with elaborating the basic concept of
sandwich panel which includes the elastic and shear stresses in sandwich panel
and followed by the deflection of sandwich panel. The next stage comprehensively highlights
the theoretical concept
of the hybrid
sandwich panel. It
was clearly shown through
the developed theoretical
frameworks that the
incorporation of intermediate
layer can substantially increase the
flexural rigidity and
stiffnesses which finally
enhances the load
carrying capacity of
the new developed sandwich panel.
