Fracture and Reliability Research Institute welcomes highly qualified Ph. D and Ms. students from all over the world.

Director's Message

Hideo Miura

Toward the middle of 21st century, the operation environment for various equipment and electronic devices is going to became severer because of the improvement of their performance such as efficiency and speed. In addition, the micro texture and composition of advanced materials have become complicated. Since both elevation of operating temperature and lattice mismatch at various interfaces accelerate the diffusion of component atoms in the materials, it has become significantly important to assure the long-term reliability of materials under operation. In order to satisfy this demand, the target issues in our Fracture and Reliability Research Institute are set as the establishment of academic and technological bases on the explication of the strength and reliability of advanced materials from the view point of atomic configuration and diffusion of component atoms. The development of monitoring methods for monitoring the applied loads, detecting the degradation process of the materials, and repairing the damaged materials are other important issues for assuring the safe and reliable operation of various equipment.

Our research institute was founded in 1964 as Research Institute for Strength and Fracture of Materials. Since then, academic foundations of strength of materials, fracture mechanics under various complicated circumstances have been developed and the institute was reorganized as Research Institute for Fracture Technology in 1989, Fracture Research Institute in 1999, and Fracture and Reliability Research Institute in 2004, respectively. Now our institute consists of 6 research division: Strength Reliability of Advanced Energy and Environmental Materials, New Energy System Science, Design and Evaluation of Performance and Reliability of Advanced Functional Materials, Nondestructive Monitoring and Evaluation Research, Materials Strength under Extreme Environment (Guest Division), and Advance Electric Power Research (Joint Research with Tohoku Electric Power Co., Inc.). Various interdisciplinary research activities have been conducted actively; development of new evaluation and design methods for long-term reliability of materials, electronic devices, equipment used in various energy plants strength and reliability of earth energy system and energy cycle, development of onーline monitoring system for evaluating integrity of materials and structures, explication of fracture mechanics in nano-scale based on multi physics computational science, and so on.

For the establishment of the world leading research and education bases, not a few international collaborative research have been continuing with 19 institute abroad from 11 countries. These international collaborations mainly consist of the integration of experimental and analytical researches on the explication of the dominant factors of the integrity of structures and materials under operation of power plants on the bases of atomic scale analyses. The expression mechanisms of the performance and reliability of advanced materials and their degradation mechanisms have been elucidated quantitatively based on the scientific rationale. International symposiums are organized every year with these collaborators and more than 600 students have attended the symposiums in this decade. This kind of exchange program activates the interdisciplinary and international researches among young researchers and students, and thus, the world-leading researchers and engineers have been produced continuously through research activities in our institute.

We would like to continue contributing the establishment of the safe and reliable society in the 21st century through the academic basis of security science for energy systems and producing the next generation of young leaders in both academic and industrial fields. I really thank all the precursors and supporters of our institute over the years from the bottom of my heart and I look forward to your further guidance and encouragement in the future. Thank you very much in advance for your continued support.
