Abstract Double-Double (DD) laminates are novel layups made up of two groups of angle plies. The assembly of local sub-ply blocks provides homogenized material properties and can achieve the unique laminate layup for the whole structure with different sub-ply block repeats. However, the thickness thinning will bring buckling forward leading to structural failure. Here we work on searching the optimal thickness tapering strategy of DD laminates to achieve the highest buckling load with the given structure weight. The DD laminate is modelled as a shell with the thickness for each element defined as different repeats of More >
