DESCRIPTION:Imagine repairing damage to your car by applying heat\, or ret
 rofitting buildings and bridges in hours instead of weeks\, or deploying e
 xtra-terrestrial habitats autonomously. These ideas may seem science ficti
 on\, but they might be achievable with architected materials. Architected 
 materials can exhibit extraordinary and unusual properties. These material
 s typically consist of periodic unit cells. By tailoring the features of t
 he unit cells\, we can enable novel properties like superelasticity\, nega
 tive Poisson's ratio\, negative thermal expansion\, and more. These specia
 l properties mean we can address grand challenges in civil engineering in 
 new ways. In this seminar\, I will describe the development of one class o
 f architected materials known as Analogs for Shape Memory Alloys (ASMAs). 
 I will walk through my development of a methodology for creating ASMAs tha
 t exhibit temperature-induced shape recovery after large deformations\, a 
 property known as shape memory effect. During this process\, the ASMAs dis
 sipate energy but remain elastic\, another special property known as super
 elasticity. Next\, inspired by the hydration-induced shape recovery of fea
 thers\, I will show how ASMA-spring systems can exhibit shape recovery. Fo
 llowing this\, real-world applications of such materials in civil engineer
 ing and other environments will be discussed.\n\nJoin Zoom Meeting\nhttps:
