Notched graphite under multiaxial loading
(Journal article; Peer reviewed, 2017)Cylindrical specimens made of polycrystalline graphite and weakened by circumferential V-notches under mixed mode I/III loading were studied in this research. Different geometries of V-notches varying the notch opening ... -
Numerical modelling of residual stress redistribution induced by TIG-dressing
(Peer reviewed; Journal article, 2019)TIG-dressing is a technique used to improve the fatigue strength of welded joints by a remelting of the weld toe region that promotes both a smoother transition between the plate and the weld crown and a residual stress ... -
Review of the influence of non-singular higher order terms on the stress field of thin welded lap joints and small inclined cracks in plates
(Journal article; Peer reviewed, 2017)In stress analysis of cracked plates, alongside the stress intensity factor which quantifies the singular stress component perpendicular to the crack plane, the role played in crack growth by the constant term parallel to ... -
Strain energy density criterion as failure assessment for quasi-static uni-axial tensile load

The effect of loading rate on fracture energy of asphalt mixture at intermediate temperatures and under different loading modes
(Journal article; Peer reviewed, 2018)At intermediate service temperatures hot mix asphalt (HMA) concretely are subjected to different loading rates due to movement of vehicles which can significantly affect their mechanical characteristics and final service ... -
The fatigue behavior of V-notches in presence of residual stresses: Recent developments and future outcomes
(Journal article; Peer reviewed, 2017)Residual stresses, arising from welding processes or nonhomogeneous plastic deformations, broadly influence the high cycle fatigue behavior of mechanical components. The presence of V-notches leads to singular residual ... -
The Strain energy density to estimate lifetime of notched components subjected to variable amplitude fatigue loading
(Journal article; Peer reviewed, 2019)In the present paper, the approach based on the strain energy density (SED) averaged over a structural volume is reformulated to estimate the lifetime of notched components subjected to variable amplitude (VA) uniaxial ... -
Two-parameter fracture model for cortical bone
(Peer reviewed; Journal article, 2016)The analysis of the bone fracture behaviour is fundamental for prevention, diagnosis and treatment of traumas. In the present paper, an experimental analysis of the fracture behaviour of a bovine femoral cortical bone ... -
Understanding powder bed fusion additive manufacturing phenomena via numerical simulation
(Peer reviewed; Journal article, 2020)The increasing interest in additively manufactured metallic parts from industry has issued a formidable challenge to the academic and scientific world that is asked to design new alloys, optimize process parameters and ... -
V-notch tip subjected to in-plane mixed mode loading: Overview of recent results and possible future outcomes
(Journal article; Peer reviewed, 2017)The fictitious notch rounding concept is applied for the first time to V-notches with root hole subjected to in-plane mixed mode loading. Outof- bisector crack propagation is taken into account. The fictitious notch radius ...
