Biography
Prof. Landis received his bachelor’s degrees in mechanical engineering
and business from the University of Pennsylvania in 1994. He then went
on to earn my MS (1997) and PhD (1999) degrees in mechanical
engineering from the University of California at Santa Barbara. After
spending a year at Harvard University as a post-doc, he then went to Rice
University where he was a member of the Mechanical Engineering and
Materials Science faculty from 2000-2006. He joined the Aerospace
Engineering and Engineering Mechanics Department at the University of
Texas at Austin in 2007 where he is the HJ Thompson Regents Professor
of Aerospace Engineering and Engineering Mechanics. Prof. Landis’
research focuses on continuum modeling and numerical simulation of the
mechanical, electrical, magnetic and thermal behavior of materials. His
specific interests are on active/smart materials such as ferroelectrics and theses, and post-doctoral associates. Along with his advisees and
ferromagnetic shape memory alloys. He also has a broad range of
interests in the mechanics of materials, including fracture mechanics,
plasticity, micromechanics, composites, and finite element methods.

Abstract
The Smart Vehicle Concept Center (SVC) is a Phase III National Science
Foundation Industry-University Cooperative Research Center (IUCRC) that Abstract
was established in 2007 with the objective to accelerate the transition of
smart materials from the laboratory to the transportation industry. The
mission of SVC is as follows: (1) conduct basic and applied research on
advanced smart materials and structures for application to vehicle
sub-systems and components; (2) build an unmatched base of research,
engineering education, and technology transfer with emphasis on
improved vehicle performance; and (3) train the next generation of
engineering professionals with an industry-centric viewpoint to
complement fundamental understanding of experimental and theoretical
research. SVC faculty and students conduct research of common interest
to Center members, in pre-competitive mode in the spirit of the IUCRC
Program, fostering cross-pollination across the automotive and aerospace memory alloys (HTSMAs). Thus, the main objective of this research is to
industries and promoting industry-focused student training as a means to
build the employee base of the transportation sector. Although smart
materials have made inroads in vehicle design, work remains to create
pathways that allow a systematic implementation of smart materials in
mass-market vehicles and in doing so, train the next generation of
engineers as savvy smart material users and advocates. The Center has
an excellent track record of innovation and creation of translational
16 research that combines PhD-level scholarly research with classroom and
continuing education. To project this track record into the future, the
Center aims to expand its reach to underrepresented groups, develop
outreach programs, and create engineering solutions that are broadly
beneficial to society. This presentation provides an overview of Center
activities and plans.

PROCESSABILITY AND ADVANCED CHARACTERIZATION OF HIGH
TEMPERATURE SHAPE MEMORY ALLOYS

Department of Materials Science and Engineering,
University of North Texas
NiTi-based shape memory alloys (SMAs) offer a good combination of
high-strength, ductility, corrosion resistance, and biocompatibility and,
therefore, have attracted the attention of many researchers and industries.
While binary NiTi SMAs can meet the requirements of many application,
some applications require phase transformation temperatures above 115
°C, especially in the aerospace industry where high temperatures are
often observed. Prior researchers have shown that adding ternary
elements such as Au, Hf, Pd, Pt, and Zr to NiTi can increase transformation
temperatures, but most of these additions are extremely expensive,
creating a need to produce cost-effective high temperature shape
examine the relatively unexamined NiTiZr system and the NiTiHf system
for the ability to produce a cost effective and formable HTSMA.
Transformation temperatures, precipitation pathways, processability, and
high-temperature oxidation are examined, specifically using high-energy
synchrotron radiation X-ray diffraction (SR-XRD) measurements, in NiTiZr
and, briefly, in NiTiHf. Through this research, knowledge of the
precipitation pathways in NiTiZr and NiTiHf HTSMAs is extended and
methods for characterization of phases and strains using high-energy
SR-XRD are elucidated for future research in the field.
