Starting from the … WebThe thickness of the delaminated ply group (the sublaminate) was assumed to be small compared to the total laminate thickness. Finite- element and Rayleigh-Ritz methods were used for the analyses. The Rayleigh-Ritz method was found to be simple, inexpensive, and accurate, except for highly anisotropic delaminated regions.
