On Locking-free Methods for Isogeometric Large Deformation Analysis of Geometrically Exact 3D Timoshenko Beams
(Master thesis, 2015)In this thesis the geometrically exact 3D shear-flexible beam model is discretized with the Lagrangian and the NURBS basis functions, and has been used as a basis to develop a family of locking-free NURBS-based elements. ... -
On strength and stiffness of screwed-in threaded rods embedded in softwood
(Peer reviewed; Journal article, 2020)Screwed-in threaded rods with wood screw threads feature high axial capacity and stiffness and can be used as fasteners in highly resistant and stiff timber connections. The purpose of the present paper is to review the ... -
On the ballistic impact resistance of additive manufactured maraging steel targets compared to that of cast targets
(Chapter, 2023)The advent of additive manufacturing (AM) in the defence industry has introduced possibilities for customisable and optimised light-weight armour. Maraging steel is well suited to AM and takes on ultra high-strength post ... -
On the ballistic perforation resistance of a sandwich structure with aluminium skins and aluminium foam core
(Peer reviewed; Journal article, 2023)Sandwich structures have proven to be excellent energy absorbents and are found in various protective solutions. In this study, an inhomogeneous aluminium foam was used as core material in a sandwich panel with skins of ... -
On the ballistic perforation resistance of additive manufactured AlSi10Mg aluminium plates
(Journal article; Peer reviewed, 2019)Materials and structures made through additive manufacturing (AM) have received a lot of attention lately due to their flexibility and ability to customize structural components of complex geometry. One range of application ... -
On the coupling of damage and single crystal plasticity for ductile polycrystalline materials
(Peer reviewed; Journal article, 2021)A crystal plasticity model accounting for damage evolution and ductile failure in a single crystal due to the presence of voids or micro-cracks is presented. An accurate, robust and computationally efficient single crystal ... -
On the description of ductile fracture in metals by the strain localization theory
(Journal article; Peer reviewed, 2017)Numerical simulations based on the bifurcation and imperfection versions of the strain localization theory are used in this paper to predict the failure loci of metals and applied to an advanced high strength steel subjected ... -
On the determination of mechanical properties of aqueous microgels-towards high-throughput characterization
(Journal article; Peer reviewed, 2021)Aqueous microgels are distinct entities of soft matter with mechanical signatures that can be different from their macroscopic counterparts due to confinement effects in the preparation, inherently made to consist of more ... -
On the dynamic response of adhesively bonded structures
(Peer reviewed; Journal article, 2020)Fracture mechanics experiments are used to investigate the rate-dependent failure of adhesively bonded structures under different deformation modes: I, II and I/II. First, the high-rate mechanical response of the adhesive ... -
On the dynamic response of blast-loaded steel plates with and without pre-formed holes
(Journal article; Peer reviewed, 2017)The dynamic response of blast-loaded steel plates is studied both experimentally and numerically. The blast loading was generated using a shock tube facility. This is an alternative to explosive detonations where the blast ... -
