Modeling For Creep-Fatigue-Induced Damage Of Advanced High-Temperature Nuclear Reactor Steels, Julian Emmanuel Tse Lop Kun Apr 2024

Modeling For Creep-Fatigue-Induced Damage Of Advanced High-Temperature Nuclear Reactor Steels, Julian Emmanuel Tse Lop Kun

Liberty University Research Week

This study focuses on developing and applying the creep-fatigue Internal State Variable (ISV) constitutive theory for the advanced high-temperature nuclear reactor steels (e.g., 316H stainless steel) to better understand how these materials deform and fracture at high temperatures under cyclic loading condition. In particular, we consider the damage evolution in these steels when some low-cycle loading is applied with finite holding periods. As such, this problem is highly history dependent, which requires tracking the evolution of some relevant microstructural rearrangements and its related properties during these complicated boundary conditions. In this study, we apply a continuum scale ISV plasticity-damage constitutive …
