Abstract
Soft active materials describe a broad class of polymers and hydrogels that change shape in response to an external stimulus, such as temperature. The shape change can be one-way or two-ways depending the underlying physical mechanism. The materials have many exciting potential applications in biomedical devices as deployable structures and in soft robotics as actuators. My lab has been working on the development of predictive constitutive models to facilitate the design of soft active devices and structures. In this presentation, I will describe our efforts to develop physics-based models for the shape memory behavior of amorphous polymers and for thermo-responsiveness of hydrogels. I will also describe the applications of the models to the study the shape changing behavior of patterned composite structures and 3D printed structures.
Profile
Thao (Vicky) Nguyen received her S.B. from MIT in 1998, and M.S. and Ph.D. from Stanford in 2004, all in mechanical engineering. She was a research scientist at Sandia National Laboratories in Livermore from 2004-2007, before joining the Mechanical Engineering Department at The Johns Hopkins University, where she is currently a tenured Associate Professor in the Departments of Mechanical Engineering and Materials Science. Dr. Nguyen’s research encompasses the biomechanics of soft tissues and the mechanics of active polymers and biomaterials. Dr. Nguyen has received the 2008 Presidential Early Career Award for Scientists and Engineers (PECASE) and the NNSA Office of Defense Programs Early Career Scientists and Engineer Awards for her work on modeling the thermomechanical behavior of shape memory polymers. She received the 2013 NSF CAREER award and 2016 JHU Catalyst Award to study the micromechanisms of growth and remodeling of collagenous tissues. She was also awarded the inaugural Eshelby Mechanics Award for Young Faculty, the ASME Sia Nemat-Nasser Early Career Award both in 2013, and the ASME Applied Mechanics Division T.J.R. Hughes Young Investigator Award in 2015.
