Shell structures are thin, curved, lightweight, and commonly found in architecture and engineering. They are ideal for applications such as domes, roofs, and bridges because of their distinctive forms, which effectively distribute loads. Shell structures provide exceptional strength-to-weight ratios by utilizing the principles of geometry and material strength. Taking advantage of this shell, a new shell structure was developed using mimicking eggshells. Eggshell geometry was studied by emulating the intricate geometric patterns and structural efficiency of eggshells. The eggshell shape was similar to that of the shell structures. To develop the geometry, the basic dimensions of the eggshell were taken by measuring 15 egg samples, and the mean average was taken to obtain an optimized geometry, which was further analyzed using ABAQUS software. This project aimed to utilize analytical techniques and computational modeling to harness the strength and low weight of eggshells to construct aesthetically appealing, resilient, and sustainable structures.
