About the Seminar: 
A wide range of global challenges, from modern infrastructure to space exploration and health, require the design and discovery of new multifunctional materials for sustainable engineering solutions with minimal impact in our ecosystem. Lightweight architected materials exploit the programmed distribution of matter to attain superior mechanical, acoustic, and thermal properties compared to those of traditional monolithic solids, and have thus shown unlimited potential for sustainable manufacturing, resilient structures, and bioengineering. Nonetheless, their mechanical behavior past the linear elastic regime is a complex interplay of material failure and/or structural instabilities which makes their design and analysis challenging. In this talk we will discuss our recent efforts to understand and predict: (a) the elastic instabilities of soft architected materials under out-of-plane axial loads and (b) the tension-compression asymmetry of brittle lattice metamaterials. 

About the Speaker: 
Stavros Gaitanaros is an Associate Professor at the Department of Engineering Technology at the Technical University of Denmark. Before that he was an Assistant Professor of Civil and Systems Engineering at Johns Hopkins University. He received his PhD in Engineering Mechanics from the University of Texas at Austin and then was a postdoc in the Department of Biological Engineering at MIT. He is a recipient of the Bureau Prize for Solid Mechanics by IUTAM and the Novo Nordisk Starting Grant. He currently serves as the vice-Chair of the ASME-AMD Technical Committee on Instabilities in Solids and Structures and he is the past Chair of the ASCE-EMI Technical Committee on Architected Materials.
