Abstract:
The
minimum weight
design
of a wide range of structures required
to
resist compressive
loading is
considered.
Items
which
have been
analysed in detail include
struts of various sorts, thin plates,
honeycomb core sandwich panels, wide column stiffened panels, stiffened
panels with optimised support
locations,
and cylindrical shells
stiffened
by
axial stiffners and rings.
A further
study
is
concerned
with the effects of
imperfections
on a tower
with corrugation stiffened
walls,
loaded in
compression. -
Except for the corrugated tower, each analysis
includes the effects
of plasticity
in
a
direct
and realistic way
by
characterising stress-strain
behaviour in the
manner suggested
by Ramberg and
Osgood.
Results for
each
type
of structure are presented, together
with
the appropriate computer programmes.
