Fatigue crack propagation analysis using XFEM for cladded C(T) specimens and its validation

Autor: Yanlong LI, Toshio NAGASHIMA, Masaki NAGAI, Tomoki SHINKO, Naoki MIURA

Publikováno v: Mechanical Engineering Journal, Vol 11, Iss 4, Pp 24-00110-24-00110 (2024)

To investigate the crack growth behavior in a cladded structure, a numerical simulation method based on the extended finite element method (XFEM) was developed. This method employs 8-node hexahedral continuum elements enriched only with the Heaviside

Characteristic Dependency of Hydrogen-Affected Fatigue Crack Growth and Crack Tip Plasticity on Low Loading Frequency in α-Iron

Autor: Guillaume Benoit, Tomoki Shinko, Gilbert Hénaff, Hadi Bahsoun, Damien Halm

Publikováno v: Metallurgical and Materials Transactions A. 51:4313-4326

Aiming to investigate the dependency of hydrogen-affected fatigue crack growth (HAFCG) on the loading frequency f, this study experimentally characterized the HAFCG in a commercially pure iron as a function of f ranging from 0.02 to 20 Hz as well as

Ductile Crack Growth Resistance and Rotation Behavior of Miniature C(T) Specimen

Autor: Masato Yamamoto, Tomoki Shinko

Publikováno v: Volume 1: Codes and Standards.

A utilization of a miniature compact tension (Mini-C(T)) specimen is expected to enable effective use of limited remaining surveillance specimens for the structural integrity assessment of a Reactor Pressure Vessel (RPV). For developing a direct frac

Controlling factors and mechanisms of fatigue crack growth influenced by high pressure of gaseous hydrogen in a commercially pure iron

Autor: Gilbert Hénaff, Damien Halm, Guillaume Benoit, Tomoki Shinko

Publikováno v: Theoretical and Applied Fracture Mechanics. 112:102885

This paper proposes an extended discussion of experimental results previously published by the authors and from literature about fatigue crack growth influenced by high pressure of gaseous hydrogen in a commercially pure iron. Firstly a summary of th
