The Nadai Medal goes to Dr. Ellen M. Arruda for pioneering
and impactful research in polymer and tissue mechanics.
Professor Ellen M. Arruda is the Tim
Manganello/BorgWarner Department Chair
of Mechanical Engineering, and the Maria
Comninou Collegiate Professor of Mechanical
Engineering at the University of Michigan.
She also holds courtesy appointments in
Biomedical Engineering and in Macromolecular Science and
Engineering. Professor Arruda earned her B.S. degree in
Engineering Science (with Honors) and her M.S. degree in
Engineering Mechanics from Penn State, and her Ph.D. degree
in Mechanical Engineering from MIT.
Professor Arruda teaches and conducts research in the areas
of theoretical and experimental mechanics of macromolecular
materials, including polymers, elastomers, composites, soft
tissues and proteins, and in tissue engineering of soft tissues
and tissue interfaces. Her recent honors and awards include
the 2019 Nadai medal from the American Society of Mechanical
Engineers, the 2018 Rice medal from the Society of Engineer-
ing Science, the 2015 Outstanding Engineering Alumnus Award
from the Pennsylvania State University, the 2014 Distinguished
Faculty Achievement Award from the University of Michigan,
the Ann Arbor Spark Best of Boot Camp award 2012, and
the 2012 Excellence in Research Award by the American
Orthopaedic Society for Sports Medicine.
Professor Arruda has more than 100 papers in scientific
journals. She also holds eleven patents. Her H-index is 32 (ISI).
Professor Arruda is a Fellow of the American Society of
Mechanical Engineers, the American Academy of Mechanics,
and the Society of Engineering Science. She is a member of
the National Academy of Engineering (class of 2017). She is
currently President of the American Academy of Mechanics.
Obtaining the Mechanical Properties of Soft Tissues –
Challenges and Opportunities
Characterizing the mechanical properties of the soft tissues of
the knee has been a major focus of my lab for the past several
years. Obtaining the mechanical properties of soft tissues is
challenging for a number of reasons, the first of which is that
they are very soft, and direct gripping is fraught with problems.
They are also anisotropic, therefore testing in multiple directions
and deformation states is typically required. Our interest in
developing full-knee computational models necessitates
accurate constitutive models of the soft tissues of the knee.
Finite element (FE) models of the knee can provide specific
information on individual tissue contributions with respect to
global joint function, as well as the coupling and coordination
among tissues during macroscopic joint motions. Computa-
tional models offer precise, full-field, and complete descrip-
xxvi tions of deformation manifesting from normal motions, injury
causing activities, injured and diseased joints, and reconstruc-
tive procedures. FE models further have the potential to
In this talk I will show how geometric effects, heterogeneous
as subject-to-subject variability in the tensile response of
the anterior cruciate ligament (ACL). I will also demonstrate
via computational simulations that uncertainties in fully
characterizing the anisotropic response of the ACL leads
to vastly different joint kinematics and tissue level strain
predictions. I will conclude with a discussion of the advent of
full-field methods and the tremendous opportunity they afford
to overcome challenges in characterization of the nonlinear,
anisotropic mechanical properties of soft tissues.

FRANK KREITH ENERGY AWARD
Gang Chen, Ph.D., Carl Richard Soderberg Professor of Power
Engineering at the Massachusetts Institute of Technology,
Cambridge MA
Gang Chen is currently Carl Richard
Soderberg Professor of Power Engineering at
Massachusetts Institute of Technology (MIT).
Gang Chen served as the head of the
Department of Mechanical Engineering at MIT
from July 2013 to June 2017. He directs the
Solid-State Solar Thermal Energy Conversion Center, an
Energy Frontier Research Center funded by the US Department
of Energy. Gang Chen’s research focuses on nanoscale
transport and energy conversion phenomena, and their
applications in energy conversion, storage and utilization.
He made seminal contributions to the understanding of heat
conduction in nanostructures via both modeling and
experimental studies. He and his collaborators exploited the
unique nanoscale heat conduction physics to advance
thermoelectric materials for energy conversion and create
high thermal conductivity materials for thermal management.
On thermal radiation, his group developed a method to
measure radiation heat transfer between two surfaces down to
tens nanometer separations and experimental demonstration
that radiative heat transfer at such small spacings can exceed
the prediction of the Planck blackbody radiation law by three
orders of magnitude. By exploring micro/nanoscale transport
phenomena, Gang Chen’s group is advancing a wide range
of technologies such as thermoelectric cooling and power
generation, solar thermal and solar photovoltaics, desalination
and waste water treatment.
Nanomaterials and Structures for Efficient Utilization of
