The papers compiled in this volume are based on talks and posters given at the International Conference on "Statistical Mechanics of Plasticity and Related Instabilities", (SMPRI 2005), held at the Materials Research Center of the Indian Institute of Science, Bangalore, India, from August 29 to September 2, 2005. Our aim in organizing SMPRI 2005 was to promote and enhance interactions between researchers from the statistical physics, materials science and solid mechanics communities. While predicting the (macroscopic) deformation properties of materials is a classical topic of materials science and materials mechanics, statistical physicists have become increasingly interested in the collective processes which control the irreversible deformation of matter on microscopic and mesoscopic scales. The SMPRI 2005 meeting has been a forum for the exchange of concepts, research ideas, and results among these communities. We hope that the contributions contained in this proceedings volume will not only help to continue and deepen this exchange, but also to disseminate the results beyond the, necessarily limited, circle of the actual participants. We want to thank all contributors for the work in preparing their manuscripts. We are grateful to the institutions which have supported this conference, in particular the Asian Office for Aerospace Research and Developement (AOARD/AFOSR), the Jawaharlal Nehru Center for Advanced Scientific Research, the Indian Center for Scientific and Industrial Research, the Indian Defense Research and Developement Organization, The Abdus Salam International Center for Theoretical Physics, Italy, the Indian Institute of Science, in particular the Center for Condensed Matter Theory and Materials Reseach Center, the Department of Science and Technology, India, the Materials Research Society of India, and the Karnatake State Center for Science and Technology. We would also like to thank the staff and students of Materials Research Center, Indian Institute of Science, who have worked hard to make the SMPRI conference a success. Our special thanks go to professor G. Ananthakrishna for his pioneering work in introducing concepts of statistical mechanics and 'nonlinear science' into materials science and engineering. To him this volume is dedicated.
