General considerations, a numerical procedure, and several examples fo
r the optimization of corrugated claddings are presented. The objectiv
e of this study is to minimize bending stresses due to bending moment
acting on the cladding by designing the appropriate profiles that sati
sfy the imposed dimensional constraints. A numerical procedure, termed
the method of local variation, is proposed for a systematic improveme
nt in the geometry of the optimized profile, and solutions are verifie
d against some limiting cases. This method of local variation is used
to optimize the cross-sectional geometry of corrugated cladding using
constraints on the coverage, the contour length, and the height of the
cross section. The procedure is also extended to include the effects
of additional panels added to both sides or to one side only. The resu
lts indicate that the simple corrugated profile with no added panels i
s the most effective in terms of providing maximum section modulus for
a given coverage and volume of material. The use of optimal core prof
iles has been shown to result in considerable improvement when compare
d to simple shapes.
