“…The stress corrosion cracking (SCC) of cladding tube structures caused by a pellet-clad interaction (PCI) seriously threatens the operation safety of nuclear facilities [1][2][3][4]. In order to ensure the structural integrity of nuclear fuel cladding during service, it is necessary to accurately calculate the stress and strain levels of cladding materials in service conditions.…”

This paper describes the formulations for the viscoplasticity of metals based on the Chaboche and Delobelle model. The implementations of the viscoplastic models were detailed herein and then implemented via user subroutines for material models (UMAT) in ABAQUS. Two typical metals, i.e., 316 Stainless Steel and Zircaloy-4, were chosen as examples and their viscoplastic behaviors were captured. Numerical simulations are compared to reported experiments in order to validate the models and the UMAT codes. The typical viscoplastic behaviors of both metals, such as stress relaxation and creep, were captured well through the available experiments. We have publicized all the data and codes.
