Effect of low temperature on fatigue crack propagation rates of DH36 steel and its butt weld
Zhao, Weidong; Feng, Guoquing; Zhang, Ming; Ren, Huilong; Sinsabvarodom, Chana (Peer reviewed; Journal article, 2019)As common marine steel for polar ships, the fatigue crack propagation rates of DH36 steel at low temperature have a crucial influence on the evaluation of the fatigue strength of polar ships. The purpose of this paper is ... -
A Framework for Structural Analysis of Icebreakers during Ramming of First-Year Ice Ridges
Zhao, Weidong; Leira, Bernt Johan; Høyland, Knut Vilhelm; Kim, Ekaterina; Feng, Guoqing; Ren, Huilong (Peer reviewed; Journal article, 2024)This paper presents a framework for structural analysis of icebreakers during ramming of first-year ice ridges. The framework links the ice-ridge load and the structural analysis based on the physical characteristics of ... -
A Probabilistic Framework for the Fatigue Damage Assessment of Ships Navigating through Level Ice Fields
Zhao, Weidong; Leira, Bernt Johan; Kim, Ekaterina; Feng, Guoqing; Sinsabvarodom, Chana (Journal article, 2021)For ships navigating in ice-covered waters, fatigue damage due to ice loads is an important issue. The purpose of this paper is to provide ship researchers and engineers with a simulation-based procedure for a probabilistic ... -
Temperature-dependent characteristics of DH36 steel fatigue crack propagation
Zhao, Weidong; Feng, Guoqing; Ren, Huilong; Leira, Bernt Johan; Zhang, Ming (Peer reviewed; Journal article, 2020)DH36 steel is a widely used material in marine engineering. The fatigue crack propagation rates of DH36 steel at low temperatures has a crucial influence on the fatigue strength of structures operating in polar environments. ...
