DESCRIPTION:    In light of today’s increasing focus on sustai
 nability\, there is a strong demand for the develo
 pment of lightweight materials\, both to reduce fu
 el consumption and raw materials usage. Architecte
 d cellular materials have great potential in this 
 regard. They are hybrid materials consisting of a 
 solid combined with pockets of air (voids)\, makin
 g them lightweight and more easily recyclable. The
 y also have tailorable material properties (i.e. b
 y carefully designing their internal architecture\
 , one can control their material properties). Thus
 \, with a thorough understanding of their structur
 e-property relationships\, it is possible to desig
 n architected materials to meet the unique require
 ments of a large variety of engineering applicatio
 ns (e.g. automotive\, aerospace\, sport\, and biom
 edical) and thus contribute to solving many global
  sustainable development goals.\n    In the past\,
  traditional manufacturing processes were limited 
 to producing two main types of macrostructures: hi
 ghly stochastic foams or uniform periodic structur
 es. Between these two extremes of stochasticity\, 
 there is a large untapped design space of architec
 tures that have not yet been fabricated nor explor
 ed\, resulting in a gap in the knowledge base arou
 nd architected materials. With the recent emergenc
 e of additive manufacturing (and rapid prototyping
 ) techniques\, researchers can now fabricate a muc
 h larger spectrum of cellular materials with a div
 ersity of internal architectures. \n    Dr. Yu’s r
 esearch is focused on the design and mechanics of 
 architected materials with intermediate-level stoc
 hasticity\, referred to as heterogeneous architect
 ed materials (HAMs). Thus far\, his research group
  (“Hybrid 3D”) has shown that there is great poten
 tial to improve strength or toughness through the 
 development of HAMs with mesoscopic geometries tha
 t mimic natural geometries observed in polycrystal
 line solids (e.g. graphene) as well as other bio-s
 tructures (e.g. insect eyes\, beehives). This geom
 etrical strengthening effect may serve as a less c
 ostly and potentially more sustainable alternative
  to traditional alloying techniques. In this semin
 ar\, Dr. Yu will provide a summary of his research
  program on HAMs and will discuss their future pot
 ential applications.\n
