A New Algorithm Can Help Improve the Design of Cell Phone Materials
New research published in Scientific Reports has revealed that a plain but robust new algorithm can help engineers improve the design of cellular materials used in various applications, from defense, biomedical to intelligent structures and the aerospace sector.
How cell materials perform can be uncertain, so calculations to help engineers predict how they will react to a specific design, a given set of loads, conditions, and constraints, can help maximize your design and performance subsequently.
Research collaborators from Swansea University’s Faculty of Science and Engineering, Indian Institute of Technology Delhi, and Brown University in the United States have found that performing specialized calculations can help engineers find the optimal microstructure for used cellular materials for a wide range of purposes, from advanced aerospace applications to used stents for blocked arteries.
Research co-author Dr. Tanmoy Chatterjee reported, “This article is the result of a year of sustained collaborative research. The research results illustrate that uncertainties at the microscale can dramatically impact the mechanical performance of metamaterials. The breakthrough formulation for them he achieved new microstructure designs by employing computational algorithms that follow the evolutionary principles of nature. “
Another co-author, Professor Sondipon Adhikari, said: “The approach used in the algorithm allowed us to achieve extreme mechanical properties involving negative Poisson’s coefficient (auxetic metamaterial) and modulus of elasticity. The ability to manipulate extreme mechanical properties through new designs of ideal microarchitecture will open up new possibilities for fabrication and applications.”
