Research

Metallic materials such as iron, steel, and aluminum and polymeric materials such as resins, fibers, and rubber, which are indispensable for our daily life, are developed for application under severe environment and weight reduction of structures. To enhance formability and reliability of the advanced materials, we are expecting the construction of theoretical models that can understand the mechanical properties based on the microscopic behavior of the material and express the deformation behavior of the advanced material.

In this laboratory, complicated behavior of materials is calculated using Multiscale Plasticity that simultaneously express phenomena of different scales such as an atomic scale on crystal structures and a continuum scale on macroscopic structures. Furthermore, we aim to unite the data obtained by experiment with computational research and to create new prediction.

ナノインデンテーション法によるTRIP鋼の力学的特性評価

Evaluation of Mechanical Properties of TRIP Steels by Nanoindentation Method

Transformation Induced Plasticity, namely TRIP, is one of the plastic deformation modes. TRIP occurs due to crystal structure changes and is utilized as a cutting-edge material called TRIP steels. TRIP steels used as material for automobiles show high strength, good ductility, and excellent shock absorption properties. Research is conducted on TRIP steels to improve their mechanical properties. However, conventional measurement tests for a macroscopic mechanical response do not reveal the microscopic phase transformation mechanism of TRIP steels. In this study, we evaluate the local mechanical behavior of TRIP steels by nanoindentation tests and attempt to reveal the mechanism of TRIP phenomena.
