Latest Patents
Kouhei Ando holds a patent for an "Estimation method of stress and strain history in cement-based composite materials and calcite particle aggregates." This patent describes a method for measuring stress history in a simple form, which is widely applicable to various types of structural materials with differing elastic moduli. The method involves embedding a large number of calcite particles as stress sensors within a cement-based composite material that can elastically deform when subjected to external forces. The twin-crystal density of the calcite particles is measured after the application of external force, allowing for the conversion of this density into strain using an approximate formula. This formula relates the strain generated in the composite material to the twin-crystal density of the calcite particles, enabling the estimation of stress history.
