Latest Patents

Sakaguchi holds a patent for an "Estimation method of stress and strain history in cement-based composite materials and calcite particle aggregates." This invention provides a simple and widely applicable method for measuring stress history in various structural materials with differing elastic moduli. The method involves embedding a large number of calcite particles as stress sensors within the composite material. After applying an external force, the twin-crystal density of the calcite particles is measured. This density is then converted to strain using an approximate formula, which is independent of the composite material's modulus. The strain is further converted to stress using the elastic modulus of the composite material, allowing for the estimation of stress and strain history.
