Tariq Khraishi is an Associate Professor of Mechanical Engineering at the University of New Mexico. His research work is in the areas of mechanics and materials science, as well as in the scholarship of teaching and learning. In particular, he has been involved in modeling, theoretical and experimental research in biomechanics, dislocation dynamics, eigenstrain theory and modeling, fracture mechanics, nanomaterials, composites, irradiation damage in materials, void growth and interaction in superplastic materials, heteroepitaxy and stresses in thin films, as well as active learning in engineering courses. He is a fellow of ASME and has published over 100 refereed works, including another textbook on materials science/engineering.Yu-Lin Shen is currently a Professor of Mechanical Engineering at the University of New Mexico. He received his Ph.D. in engineering from Brown University in 1994, and was a post-doctoral research associate at the Massachusetts Institute of Technology before joining the faculty of the University of New Mexico in 1996. Professor Shen is widely recognized for his research in mechanical behavior of materials, especially in modeling. His numerical modeling experience spans disparate length scales from the continuum level down to atomistics, focusing on mechanical issues related to thin films, composite materials and microelectronic devices, and packages. In 2005 Professor Shen was elected a fellow of the American Society of Mechanical Engineers (ASME). He is also the author of the book Constrained Deformation of Materials, published by Springer in 2010.
