The aim of this project was to understand the mechanical design of mineralized cuticle from the exoskeletons of marine decapod crustaceans (Homarus americanus, Cancer pagurus). To achieve this, we performed a detailed analysis of microstructure and chemical composition and the characterized the resulting macro- and micromechanical properties on the material level both in dry state and in the natural, hydrated state.[1]
