total thickness are h(total)=4.61mm. The optimum designs from Example 1 and 
exam
le 2 are compared and given in Table 4. We find that the total thickness or 
weig
t is reduced by 20% when the ply group angles are also considered as design 
var
bles. It
is recognized that the optimum design of ply orientations is very important 
to
lly take advantage of the directional effect on the stiffness of composite m

als.
