Interfaces play a key role in determining the thermal, mechanical, electrical, electronic and even biological behavior of materials and structures. The significance of their roles depends on the level of discontinuity of the relevant property and on the external conditions imposed. While continuum theories may be constructed in selected applications, a much larger class of problems involving nanoscale materials, highly heterogeneous materials, and even biological materials beg different approaches. Interfaces influence fracture, thermal (conductivity, expansion), mechanical, and shock wave response differently. A general overview of the mechanics of interfaces with specific cases involving superplastic materials, composite materials, nanoscale electronic materials,and human brain will be presented to discuss these aspects.


Dr. Chandra is a Professor in the Department of Engineering Mechanics and Associate Dean for Research in the University of Nebraska--Lincoln College of Engineering. He joined the College in 2006. He previously was a named Professor in the Department of Mechanical Engineering in the Florida A & M University / Florida State University College of Engineering for 20 years. Superplasticity, composite materials, and computational mechanics are the areas which Dr. Chandra has published over 140 publications including 70 in archival journals and 4 books. He is a Fellow of American Society of Mechanical Engineers (ASME). He is an associate editor of ASME Journal of Materials and Technology, the premier journal in the field, Journal of Mechanics of Advanced Materials and Structures, and ASTM Journal of Engineering Materials and Performance, and in the editorial board of CMES: Computer Modeling in Engineering and Sciences.
