研究概要

Hydrogen compatible materials

Develop and verify lifetime prediction methodologies for behavior of materials used in hydrogen infrastructure. Our approach integrates mechanical property testing at the microscale, microstructural analyses and transmission electron microscopy observations of the deformation processes at the micro- and nano-scale, first principle calculations at the atomic scale, and finite element modeling and simulation at the micro- and macro-level.

Constitutive behavior of materials

Modeling and simulating constitutive response of materials in adverse chemomechanical and high temperature environments, e.g. high temperature hydrogen attack and creep response, by integrating analytical and numerical approaches with experimental characterization and measurement of the deformation of materials at the micro- and macro-scales.
