This paper reviews different approaches used to analyze buckling and optimization of composite lattice
structures. In the preliminary design, a smeared stiffness approach can be used to calculate global buckling analytical
results for smeared lattice panels, cylinders and conical shells. However, it is difficult to get the analytical results for
complicated lattice structures with unbalanced laminate and stretching鄄bending鄄shearing coupling. So FEA (finite ele鄄
ment analysis) is used to get realistic mechanical response through nonlinear simulation. Simultaneously, the paper
also introduces other numerical methods (i. e. ,genetic algorithm). Finally, some experimental methods employed to
investigate fracture mechanisms and post鄄buckling behavior of lattice structure are also introduced
