A simulation methodology is proposed which combines linear elastic analyses of
large scale laminated composite structures and nonlinear unit cell predictions
to account for local nonlinear material behavior at the ply level.
In a two-step procedure nonlinear unit cell simulations are conducted first.
The results can then be used to draw "energy dissipation envelopes" in stress
and strain space and to perform post-processing on linear large scale
Based on the concept of energy dissipation monitoring, the macroscopic material
point exertion is assessed.
The methodology is demonstrated using a generic nacelle structure built from
laminated textile composites.
