Analysis of the plastic zone near the crack tips under the uniaxial tension using ordinary state‐based peridynamics
(Journal article; Peer reviewed, 2018)In this paper, the plastic model of ordinary state‐based peridynamics is established. The size and shape of plastic zone around crack tips with the different inclination angles are simulated using ordinary state‐based ... -
Application of EMC-J criterion to fracture prediction of U-notched polymeric specimens with nonlinear behaviour
(Journal article, 2018)The main purpose of the present research paper is to investigate applicability of a new energy‐based failure prediction model, called EMC‐J criterion, to predict the critical loads of U‐notched polymeric samples having a ... -
Calibration of the potential drop method by means of electric FE analyses and experimental validation for a range of crack shapes
(Journal article, 2018)In experimental fatigue tests, it may be necessary to identify the onset of crack initiation, which is often defined at a given (short) crack length. Different experimental techniques are available to estimate the initiated ... -
Collection of experimental data for multiaxial fatigue criteria verification
(Peer reviewed; Journal article, 2020)The present paper aims to propose data from incisive multiaxial fatigue experimental tests which results from the analysis of several works within current literature. Approximately 200 experimental datasets have been ... -
Critical review of turbulence models for CFD for fatigue analysis in large steel structures
(Journal article, 2018)The determination of wind‐induced fatigue load in large structures and buildings with complex geometries, which do not fall in typical cases of building codes and standards, represents a consuming task, and it is usually ... -
Effects of different indentation methods on fatigue life extension of cracked specimens
(Journal article; Peer reviewed, 2018)In this paper, 3 different indentation methods have been investigated for crack arresting and fatigue life enhancement of cracked components. The influence of residual stresses induced by indentation on fatigue crack growth ... -
Fatigue assessment of as‐built and heat‐treated Inconel 718 specimens produced by additive manufacturing including notch effects
(Journal article; Peer reviewed, 2020)The fatigue behaviour of notched and unnotched specimens produced by additively manufactured Inconel 718 were analysed in the as‐built and heat‐treated conditions. The surfaces display high roughness and defects acting as ... -
Fatigue assessment of steel load-carrying cruciform welded joints by means of local approaches
(Journal article, 2018)In this paper, local approaches are employed to analyse stress distributions, local fatigue indicators of weld toe, and weld root in load‐carrying cruciform welded joints (LCWJs). An extension of previous available equations ... -
Fatigue of additively manufactured 316L stainless steel: The influence of porosity and surface roughness
(Journal article; Peer reviewed, 2019)The fatigue behaviour of additively manufactured (AM) 316L stainless steel is investigated with the main emphasis on internal porosity and surface roughness. A transition between two cases of failure are found: failure ... -
Fatigue properties of AA6060-T6 butt welds made by hybrid metal extrusion & bonding
(Peer reviewed; Journal article, 2020)The present investigation is concerned with high‐cycle axial fatigue testing of a 2‐mm AA6060‐T6 hybrid metal extrusion & bonding (HYB) butt weld produced in the solid state using AA6082 filler metal addition. The results ... -
Fracture analysis of V‐notched rubbers: An experimental and theoretical study
(Journal article, 2018)In this study, the rupture load in rubbers weakened by sharp V‐notch is investigated under mode I loading. To this end, first, mode I fracture tests are performed on V‐notched samples made of styrene‐butadiene rubbers and ... -
Global‐local fatigue assessment of an ancient riveted metallic bridge based on submodelling of the critical detail
(Journal article; Peer reviewed, 2018)Increasing traffic demands (ie, load intensity and operational life) on ancient riveted metallic bridges and the fact that these bridges were not explicitly designed against fatigue make the fatigue performance assessment ... -
High cycle fatigue life estimation of materials processed by laser powder bed fusion
(Journal article, 2019)The fatigue life of metal components is known to depend on the surface topography. For components made by laser powder bed fusion, the roughness of the as‐built surfaces depends on the orientation of the component surface ... -
Influence of solidification defects on the fatigue behaviour of heavy‐section silicon solution–strengthened ferritic ductile cast irons
(Journal article, 2018)Mechanical and fatigue properties of heavy section solution–strengthened ferritic ductile iron (SSF‐DI) castings have been examined in this contribution. Amounts of silicon varying from 3.2 to 3.55 wt% have been used. The ... -
A new fixture for fracture tests under mixed mode I/II/III loading
(Peer reviewed; Journal article, 2019)In this paper, a new loading device for general mixed mode I/II/III fracture tests is designed and recommended. Finite element analyses are conducted on the proposed apparatus to evaluate the fracture parameters of the ... -
Novel method for the fatigue strength assessment of heavy sections made by ductile cast iron in presence of solidification defects
(Journal article, 2018)The fatigue strength of ferritic, pearlitic, and solution strengthened ferritic ductile irons taken from heavy sections and characterized by long solidification times has been assessed. Starting from the idea of Murakami ... -
On the interaction between corrosion and fatigue which determines the remaining life of bridges
(Journal article; Peer reviewed, 2018)This paper studies the prior effect of corrosion on fatigue on the growth of cracks that arise from natural corrosion in steel bridges. It is shown that these 2 effects need to be simultaneously analysed. If not, then the ... -
Stress-strain curves of metallic materials and post-necking strain hardening characterization: A Review
(Journal article; Peer reviewed, 2019)For metallic materials, standard uniaxial tensile tests with round bar specimens or flat specimens only provide accurate equivalent stress–strain curve before diffuse necking. However, for numerical modelling of problems ... -
