| Abstract Scope |
Amniotic eggs are a remarkable evolutionary innovation that enabled amniotes to thrive on land by providing an additional layer of protection through their hard, calcified shells. However, hard shells are vulnerable to cracking, posing potential threats to developing embryo inside. In this talk, I will present our work, by utilizing structural characterization, in-situ experiments, mechanical analyses and modeling to elucidate the fracture behavior and mechanical designs of avian eggs at three length scales. Fabrication of artificial eggshells and corresponding systematic mechanical experiments will be discussed to understand the underlying design principles as well. Our findings reveal that eggshells encompass controlled shell material, thickness, microstructure, and shell-membrane interfaces to prevent global fracture and protect membrane. |
