Fatigue Strength Curve for Tubular Joints of Offshore Structures under Dynamic Loading
(Journal article, 2021)Abstract Offshore structures are subjected to dynamic environmental loads (wave and wind loads). A stress-life fatigue strength curve is proposed for tubular joints which are in the splash zone area of offshore jacket ... -
Fatigue strength degradation of corroded structural details: A formula for S‐N curve
(Peer reviewed; Journal article, 2019)A formula is proposed to predict fatigue strength of corroded members and joints of steel structures. The concept of the formula is first studied from recently identified mechanism of corrosion fatigue. Hence, the corresponding ... -
Fatigue strength degradation of metals in corrosive environments
(Journal article; Peer reviewed, 2017)Structures exposed to aggressive environmental conditions are often subjected to time-dependent loss of coating and loss of material due to corrosion; this causes reduction in the cross-sectional properties of the members, ... -
Feasibility Study of a Novel Open Ocean Aquaculture Ship Integrating with a Wind Turbine and an Internal Turret Mooring System
(Peer reviewed; Journal article, 2022)Marine aquaculture has been expanded into more remote areas due to the increasing demand for high value-added fish products, bringing more challenges in fuel supply and mooring safety to open ocean aquaculture farms. ... -
FEM-based assessment of wear of stamping die
(Peer reviewed; Journal article, 2019)In sheet metal forming industry, surface damage and wear such as adhesion and ploughing of metallic sheet, is a well-known problem which reduces the tool life and quality of drawn elements. Surface defects are the consequences ... -
Field development optimization of waterflooding process using data assimilation methods
(Peer reviewed; Journal article, 2019)The application of data assimilation methods for field development optimization has been the subject of intense investigation during the past 10 years. Lately has seen remarkable progress in the ability of data assimilation ... -
Finite Element Analysis of Steel Plates with Rectangular Openings Subjected to Axial Stress
(Peer reviewed; Journal article, 2022)Steel plates with openings are among the important ship structural components used in the ship’s hull to withstand the hydrostatic forces of the ocean, which cause sagging and hogging moments at the ship’s bottom. The ... -
Finite element method-based modeling of bending under tension friction test of deep drawing quality steel sheets
(Peer reviewed; Journal article, 2019)Understanding of the effect of the friction on the sheet deformation is a key factor in design and realization of stamping process. Among others, bending under tension friction test simulates the frictional phenomena on ... -
