Non-Destructive Evaluation and Science Research Center

Role of the Non-Destructive Evaluation and Science Research Center

The Research Center was established at the beginning of the 21st century to preserve the social infrastructure and natural environment from an engineering perspective, to protect people’s lives and property for many years to come, and to contribute to peace in the world. Preservation of the social structure is expected to develop as a new field of academic study in the 21st century. "Preservation Engineering" is now a new field of academic study, but the research center plays a leading role in spreading it through society.

Research Outline

Structures made from metals have a lifespan (durable period) similar to human beings. Comparing a structure to a human being, supporting an average life of 80 years, material degradation progresses from the start of use, producing cracks at the age of 50. The structure finally breaks down at the age of 80. The research center is investigating the process of material degradation from start of use to cracking by using "dislocation" and "magnetism (attractive force exerted by a magnet)," which are two indicators that show degradation in metals, thus predicting when cracks will be generated. Supposing that conventional research is based on the prevention of disease after 50 years of age when the aging process begins, the research we are working on in the research center corresponds to health management ranging from, what we call infancy to old age. This is the first such approach in the world.
