Blending rule - Plies may be droped in the > direction starting from the key element |
Design space
Two optimization problem formulations were introduced
to incorporate blending rules.
t - Formulation ti(j,k)- binary thickness
variable indicating presence of a ply i in an element (j,k)
minimize f(q,t)
subject to gl(q,t)
>
0 l = 1,...,m
d-Formulation di(j) - distance variable indicating
number of elements a ply i occupies ina row j
minimize f(q,d)
subject to gl(q,t)
>
0 l = 1,...,m
N = maximum number of plies in each element
