DESCRIPTION:Speaker: Christian Santangelo\nhosted by Scott Waitukaitis\nAbs
 tract: The materials of biology\, from sharkskin to cartilage to wood\, re
 gularly out-perform their synthetic equivalents. Organisms can achieve thi
 s because their materials have precise geometric structures that endow the
 m with tailored mechanical properties that can often be changed in situ. I
 t has recently become possible to fabricate comparable structures through 
 3D printing\, but we still seem to understand little about how geometry an
 d mechanics are intertwined. This talk will discuss why this is a hard pro
 blem (NP-hard actually)\, and highlight new work by my group and collabora
 tors that are starting to unveil new connections between geometry and mech
 anics. This new understanding has allowed us to design materials that can 
 change their mechanical properties\, changing from rigid to floppy due to 
 the imposition of internal stresses\, and sheds light on the flexibility o
 f shells and other structures.
