This research applies a numerical study of topology optimization of laminate composite structures
by using a Finite Element
Method. In this methodology, the plies
orientation is excluded from
the optimization. The geometry-based optimization from frames of a MALE UAV fuselage structure is presented. The minimum strain energy with an optimization constraint of 20 percent of weight reduction
is used in the objective
function. Before the primary
analysis, benchmark studies
of topology optimization without considering orientations from previously published literature are performed. The convergence studies were taken to acquire the appropriate mesh size in the FEM technique, which
utilized a four-noded shell
element. The FE analysis and optimization
results showed that the
structural design of the newly frame composite fuselage MALE UAV meets the structural strength requirements specified in the airworthiness standard STANAG 4671.
