Materials Informatics Lab
Machine-translated · View original
A lab that explores the elasticity and phase transitions of materials through mechanics and computation.
AboutAbout the lab
Understanding the elasticity of materials through mechanics and computation.
The Materials Informatics Lab (Tane Lab) studies the mechanics, phase transitions, and microstructure formation of materials.
The lab regards materials as hierarchical, complex mechanical systems spanning the nanoscale to the macroscale, and investigates them using mechanics, such as mechanics of materials and thermodynamics, together with multiple regression analysis.
The lab also works on developing measurement and analysis systems.
The lab hopes that students who join it will, through their research, combine experimental science and computational science and grow into professionals who will lead this interdisciplinary field.
Key terms
- Elastic modulus
- A value that shows how resistant a material is to deformation when a force is applied to it
- Phase transition
- A change in the state of a substance, such as its crystal structure, into another state depending on conditions such as temperature or composition
- Micromechanics
- An approach that uses theory to study the overall elastic properties of a material from its microscopic structure. Also called microscopic elasticity theory

ResearchResearch themes
The lab regards materials as hierarchical, complex mechanical systems spanning the nanoscale to the macroscale, and works on the mechanics, phase transitions, and microstructure formation of materials, as well as the development of measurement and analysis systems. It combines fundamental disciplines such as crystal elasticity theory and thermodynamics with machine learning and various kinds of programming to advance research and the development of instruments and systems.
Lowering the Elastic Modulus of Biomedical Titanium Alloys
The lab combines experimental science, computational science based on crystal elasticity theory, and machine learning (multiple regression analysis) to study the elastic properties of biomedical titanium alloys. Hierarchical factors such as crystal structure, microstructure, and texture govern these elastic properties.
Phase Transitions and Mechanical Properties of Titanium Alloys
The lab focuses on a new type of phase transition, the diffusionless isothermal omega transformation, which is governed by frozen fluctuations in alloy composition. It studies how to control the mechanical properties of materials by using this transformation, combining phase transition theory and mechanical relaxation theory.
*Illustrative imageNew Elasticity Evaluation Methods and 3D-Printed Materials
The lab is developing a new method for evaluating elastic properties, based on inverse problem analysis using multiple regression analysis. It applies this method to materials made by 3D printing (additive manufacturing) to evaluate their properties.
*Illustrative imageElucidating Elastic Properties with Microscopic Elasticity Theory
The lab studies the elastic properties of materials using the effective-mean-field theory, its own micromechanics theory based on Eshelby's equivalent inclusion theory.
