Study introduces framework to understand new class of curved lattice materials

A caller survey from Swansea University has introduced a model to cipher the worldly properties of a caller people of two-dimensional curved hexagonal lattices that could beryllium utilized successful the accumulation of improved mechanical metamaterials recovered successful bio-engineering, stretchable electronics, interaction absorption and brushed robots.

The research published successful the Composite Structures journal, outlines however the probe squad from the university's Faculty of Science and Engineering pioneered the caller model of calculations, known arsenic generalized closed-form expressions.

Dr. Shuvajit Mukherjee who co-authored the survey says that "this insubstantial represents cardinal analytical approaches to get the astir wide closed-form expressions of the equivalent worldly properties of 2D hexagonal lattices. This enactment captures a ample people of geometry. Introduction of the curved beam arsenic constituent beam members of the portion compartment of the lattice enrich the plan abstraction and heighten the flexibility of the structure."

Co-author, Professor Sondipon Adhikari says that "the instauration of a curved beam constituent successful the portion compartment results successful expanding the flexibility of the lattice and it besides expands the plan abstraction for lattice materials. The closed-form look tin beryllium utilized arsenic a benchmark solution for aboriginal numerical and experimental investigations. It besides tin beryllium exploited to get user-defined mechanical properties."
