Bio-inspired selective nodal decoupling for ultra-compliant interwoven lattices

Y. Mistry, O. Weeger, et al.

This innovative research showcases ultra-compliant interwoven lattices that achieve a remarkable tenfold compliance enhancement over traditional designs at equivalent volume fractions. The approach draws inspiration from the Venus flower basket sea sponge, providing a versatile blueprint for stiffness modulation in lattice structures. This groundbreaking work involves expertise from Yash Mistry, Oliver Weeger, Swapnil Morankar, Mandar Shinde, Siying Liu, Nikhilesh Chawla, Xiangfan Chen, Clint A. Penick, and Dhruv Bhate.

Abstract

This paper introduces a class of ultra-compliant interwoven lattices exhibiting up to a tenfold compliance improvement over traditional counterparts at similar volume fractions. This is achieved by selectively decoupling nodes and interweaving struts, inspired by the Venus flower basket sea sponge. The resulting design strategy offers a simple and near-universal method for modulating stiffness in lattice structures.
