Bufalari, G. (author), den Besten, J.H. (author), Kaminski, M.L. (author)The response of maritime structures can be multiaxial, involving predominant mode-I and non-negligible mode-III components. Adopting a stress distribution formulation based effective notch stress as fatigue strength parameter for mixed mode-{I, III} multiaxial fatigue assessment purposes, a mode-I equivalent von Mises type of failure...journal article 2024

Scheeren, B. (author), Kaminski, M.L. (author), Pahlavan, Lotfollah (author)This article presents an approach to identify naturally developed damage in low-speed bearings using waveform-similarity-based clustering of acoustic emissions (AEs) under fatigue loading. The approach is motivated by the notation that each recorded AE signal from a particular damage is defined by the convolution of the source signal, transfer...journal article 2023

Scheeren, B. (author), Kaminski, M.L. (author), Pahlavan, Lotfollah (author)In the condition monitoring of bearings using acoustic emission (AE), the restriction to solely instrument one of the two rings is generally considered a limitation for detecting signals originating from defects on the opposing non-instrumented ring or its interface with the rollers due to the signal energy loss. This paper presents an approach...journal article 2022

Bufalari, G. (author), den Besten, J.H. (author), Kaminski, M.L. (author)The predominant mode-I response of maritime structures can be multiaxial, involving out-of-plane mode-III shear components. Semi-analytical mode-III notch stress distribution formulations have been established for critical details like welded T-joints and cruciform joints, reflecting (non-)symmetry with respect to half the plate thickness....journal article 2022

Qin, Y. (author), den Besten, J.H. (author), Palkar, S.S. (author), Kaminski, M.L. (author)The characteristic far field response spectrum of welded joints – the governing fatigue sensitive locations in steel marine structures – is predominantly linear elastic, meaning mid- and high-cycle fatigue (MCF and HCF) is most important for design. Using the effective notch stress- and the total stress concept, involving respectively S<sub>e...journal article 2021

van der Horst, Menno (author), van Kreveld, Sylvia (author), Kaminski, M.L. (author)Wireless crack monitoring on ships and offshore structures based on Self Magnetic Flux Leakage (SMFL) measurements is a promising method to guarantee the structural integrity in a more effective way, leading to reduced operational costs and increased safety. For accurate crack sizing, the SMFL measurements must be interpreted correctly, also...journal article 2019

Qin, Y. (author), den Besten, J.H. (author), Palkar, S.S. (author), Kaminski, M.L. (author)Fatigue is a governing design limit state for marine structures. Welded joints are important in that respect. The weld notch stress (intensity) distributions contain essential information and formulations have been established to obtain a total stress fatigue damage criterion and corresponding fatigue resistance curve; a total stress concept....journal article 2019
