Xin, H. (author), Correia, José A.F.O. (author), Veljkovic, M. (author)The assessment of fatigue crack propagation of steel structures is essential and important especially to improve the application of high strength steel in construction. The load ratio R, reflecting mean stress effects, will be changed with crack extension in the steel structures with complicated geometry. In this paper, the Walker equation is...journal article 2021

Deshmukh, Kaustubh (author)Additive Manufacturing (AM), commonly known as 3D printing, exemplifies the recently emerging processing methodologies that aim to substitute the conventional routes, such as to produce parts with complex geometries and eliminate expensive tooling. AM also allows high degree of freedom and rapid prototyping for functional part optimization. This...master thesis 2020

Malschaert, David (author)In the course of this thesis, a research has been conducted to the application of fracture mechanics on an othotropic steel deck (OSD). Obtaining accurate predictions of crack path and fatigue life assessment were the main objectives for this thesis. As 3D crack propagation modelling in orthotropic steel decks is an arduous task, simpler studies...master thesis 2020

van den Berg, Niels (author)Orthotropic steel decks (OSDs) are susceptible to fatigue failure due to cyclic loading by heavy traffic passing the deck. These cyclic loads can cause fatigue cracks in the rib-to-deck joint. In and around the joint residual stresses are present due to the welding process. In this thesis, the effects of residual stresses on the fatigue crack...master thesis 2020

Raimondo, A. (author), Doesburg, S.A. (author), Bisagni, C. (author)In this work, an approach based on the Virtual Crack Closure Technique, included in the commercial finite element code ABAQUS, is adopted to study the propagation of delamination in composite structures under quasi-static and fatigue loads. The methodology, originally capable of simulating only delamination under quasi-static loads, has...journal article 2020

Sahu, Saswat (author)Functionally graded materials (FGMs) represent a new class of materials that consist of graded compositional and microstructural patterns allowing to tailor properties. Additive manufacturing (AM) or more commonly known as 3D-printing offers a paradigm shift in FGMs and engineering design due to its ability to produce components with complex...master thesis 2020

Fu, Qiang (author), Yi, Sinan (author), Chen, B. Y. (author), Bui, Tinh Quoc (author), Hu, Xiaofei (author), Yao, Weian (author)Numerical study on crack propagation are of great importance for structure design and assessment. In this contribution, the floating node method (FNM) is combined with the symplectic analytical singular element (SASE) to form a new crack-tip element. The four node quadrilateral crack-tip element contains a SASE for the crack tip area to...journal article 2020

Prediction of Fatigue Crack Propagation in Orthotropic Steel Decks using XFEM based on LEFM and VCCTGupta, Ravi Shankar (author)Orthotropic Steel Decks (OSDs) are widely used in various types of steel bridges due to their benefits of light weight, high load bearing capacity and speedy construction. Although many improvements in aspects of design, fabrication, inspection, and maintenance have been achieved over the years for such bridge decks, fatigue remains a...master thesis 2019

Korswagen, Paul A. (author), Longo, M. (author), Meulman, E. (author), Rots, J.G. (author)Induced seismicity in the north of the Netherlands has recently exposed unprepared, unreinforced masonry structures to considerable earthquake risk. While the ultimate-limit state capacity of the structures is vital to assess the individual’s risk, their behavior during more frequent, lighter earthquakes, leading to ‘lighter damage’, has shown...conference paper 2019

Gupta, Ravi Shankar (author), Xin, H. (author), Veljkovic, M. (author)Orthotropic Steel Decks (OSDs) are widely used in various types of steel bridges due to its benefits of light weight, high load bearing capacity and speedy construction. However, fatigue remains as the predominant problem for OSDs. Many researchers have investigated fatigue issues of welded joints through experiments but is not a cost-effective...journal article 2019

Baas, Olivier (author)In order to monitor elliptical fatigue crack growth in ferromagnetic steel using magnetic methods, analternative to the self magnetic flux leakage method must be derived as elliptical cracks can grow to significant sizes before they reach through the thickness of the plate material. An approach is sought by translating subtle changes in...master thesis 2018

Dorca, Paul (author)Damage tolerant designs are necessary for the continuous operation of aircraft engines which are subjected to harsh environmental influences during operation (e.g. large temperatures, foreign object damage of airfoils). One important aspect of damage tolerance is crack propagation which can be investigated via 3D numerical software. This Master...master thesis 2018

Deng, X. (author), Qian, Zhiwei (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)Rail squats originate from a number of sources, such as corrugations, indentations and welds. A five-year continual field monitoring study was performed on squats induced by corrugations. This study indicated that a small black depression formed at the corrugation under wheel-rail dynamic forces, and then, a primary crack typically initiated...journal article 2018

Bransen, M. (author)The term Leak-Before-Break (LBB) refers to a well-established safety criterion used to assess whether cracked tanks or pipes can leak detectable amounts of fluid as a warning before catastrophic failure occurs.

Slobbe, A.T. (author)The crack band approach (in the smeared crack concept) is widely used for the modeling of concrete fracture and is an important analysis technique within advanced engineering. However, the simulations can be impeded by mesh-induced directional bias. Cracks prefer to propagate along continuous mesh lines, which causes a dependency of the...doctoral thesis 2015

Zeng, Y. (author)For the industry of pipe-laying, the propagation of a crack can finally lead to failure of the structural components. This may cause catastrophic consequences for environment, economy and even lives of people. Therefore, the mechanical assessment of crack-like defects is of great importance in engineering practice. For non-linear problems,...master thesis 2015
