Quasi-cleavage hydrogen-assisted cracking path investigation by fractographic and side surface observations
(Journal article; Peer reviewed, 2019)Despite recent substantial advances in understanding of hydrogen embrittlement (HE), many important aspects of this widespread phenomenon remain a subject of debates. Particularly, remarkably different opinions have been ... -
Simulation of ductile fracture in aluminium alloys with random or strong texture using heuristic extensions of the Gurson model
(Peer reviewed; Journal article, 2022)Ductile fracture of two high-strength aluminium alloys in temper T6 is investigated using heuristic extensions of the Gurson model with non-quadratic yield criteria. Simulations of tensile tests on smooth and notched ... -
Simulation of ductile-to-brittle transition combining complete Gurson model and CZM with application to hydrogen embrittlement
(Journal article; Peer reviewed, 2022)A general simulation framework for modelling ductile-to-brittle transition in metals is proposed. The method combines the complete Gurson model and cohesive zone model, which brings ductile and brittle fracture mechanisms ... -
T-stress effects on fatigue crack growth – Theory and experiment
(Journal article, 2018)The effects of specimen geometry on the fatigue crack growth rate and the number of elapsed cycles have been investigated experimentally and theoretically for Al 7075-T6 using four different cracked specimens with positive ... -
Temperature dependence of the shear strength in adhesively bonded joints reinforced with multi-walled carbon nanotubes
(Journal article; Peer reviewed, 2018)In this paper, the temperature dependence of the strength of adhesively bonded shear lap joint reinforced with multi-walled carbon nanotubes (MWCNTs) was studied. The results showed that increasing the testing temperature ... -
Testing and modelling of annealed float glass under quasi-static and dynamic loading
(Journal article, 2018)In recent years, a considerable number of studies has been carried out to analyse the behaviour of laminated glass plates under blast loading by the use of the finite element method. This has proven to be quite challenging, ... -
Understanding the fracture behavior of brittle and ductile multi-flawed rocks by uniaxial loading by digital image correlation
(Journal article; Peer reviewed, 2018)Fracturing behavior of ductile multi-flawed rock mass is very different from those of brittle multi-flawed rock mass. However, there is a very vague distinction of the fracture mechanism of ductile multi-flawed rock mass ... -
Using unit cell simulations to investigate fracture due to compression-tension loading
(Journal article; Peer reviewed, 2016)Experiments regarding impact against X65 steel pipes show that fracture typically arises in areas subjected to large compressive strains before tension. Fracture surfaces from these areas are brittle in character despite ... -
Viscous regularization for cohesive zone modelling under constant displacement: an application to hydrogen embrittlement simulation
(Journal article; Peer reviewed, 2016)The convergence problem during the cohesive zone modelling of hydrogen embrittlement in constant displacement scenario is attributed to the numerical instability which is studied analytically in the present work. The ... -
Wedge splitting test of wood for fracture parameters estimation of Norway Spruce
(Peer reviewed; Journal article, 2020)Crack evolution in wood from Norway Spruce during mode I wedge splitting tests was measured using a Digital Image Correlation (DIC) system. The resulting series of deformation fields were post-processed in order to obtain ...
