Abstract:The bionics-based integrated analysis and design is performed for
   loading capacity and thermal protection of multilayer thin-walled
   structures through mechanical computations and optimization. The
   prototype of the thin multilayer model is inspired by the shell of
   snails that live on the floor of Indian Ocean. The layering model
   considering force and heat transfer is created and analyzed for
   characteristics of thermal protection and loading capacity. Through an
   example of three dimensional aerodynamic heating and a structural
   optimization based on genetic algorithm, it is demonstrated that the
   bionics-inspired multilayer structure has the best distribution of
   materials, and can be adopted as a superior prototype for the design of
   thermal protection and loading capacity.
