Advances in Materials Science and Engineering, 2019 A highly anisotropic toughness behavior has been revealed on a forged AA6061 aluminum alloy by toughness tests with CT specimens. The toughness values with specimens loaded on the longitudinal direction are larger than that loaded on the transverse ...

Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 4, December 2023., 2023 Abstract Ductile materials are used in many applications such as hydrogen storage and transport, energy plants and additively manufactured components. High safety standards are vital for such applications, which underline the necessity of thoroughly investigating ductile failure to ensure safety and increase components efficiency.

AA5052-PVC-AA5052 (Al-PVC-Al) Sandwich Sheets Forming Analysis through In-Plane Plane Stretching Tests. [PDF]
ScientificWorldJournalSheet metal forming is one of the key processes for the automotive sector to be considered. Sheet metal formability is being tested as received, joining them with different welding/joining processes (i.e., tailored blanks) and making them as sandwich forms to reduce the total weight of the body.

Tensile behaviour of welded S700 rectangular hollow section X‐joints
ce/papers, Volume 6, Issue 3-4, Page 1519-1523, September 2023., 2023 Abstract High‐strength steels (HSS) have higher strength but lower ductility compared to mild steels. A material factor (Cf) and a 0.8fu restriction on the material design yield strength (fy) are stipulated to reduce the design resistance of welded HSS hollow section joints in the newest version of prEN 1993‐1‐8 (2022), given the low ductility of HSS ...

Fatigue crack growth modeling considering a hybrid propagation strategy
Fatigue &Fracture of Engineering Materials &Structures, Volume 46, Issue 4, Page 1613-1626, April 2023., 2023 Abstract Fatigue results from the occurrence of several damage mechanisms and their interactions. The cyclic plastic strain and damage accumulation at the crack tip are widely pointed as the main agents behind fatigue crack growth (FCG). In this work, the authors propose the prediction of FCG through a node release numerical model that offers several ...

Fatigue &Fracture of Engineering Materials &Structures, Volume 45, Issue 9, Page 2427-2442, September 2022., 2022 Abstract The recently developed edge tracing (ET) method allows to estimate the radial deformation in axisymmetric tensile specimens via analysis of digital images recorded during the experiments. Images are processed to detect the sample's contours and therefore estimate the minimal cross‐section diameter.

Science and Technology of Nuclear Installations, Volume 2022, Issue 1, 2022., 2022 The material mechanical properties and crack propagation behavior of dissimilar metal welded joint (DMWJ) of pressurized water reactor (PWR) was investigated. In this research, the mechanical parameters of the cladding layer materials (304L‐SA508) of the DMWJ in PWRs were obtained by the continuous indentation test.

The Effect of Compression on the Void Coalescence under Strong Dynamic Loading
Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 The void coalescence under strong dynamic loading is a significant spallation process for ductile metals. Since the spallation is basically dominated by tension waves, most void coalescence studies have focused on the tension effect. However, it is known that in spallation, the material initially undergoes a strong compression wave, and then an ...

Multiaxial static strength of a 3D printed metallic lattice structure exhibiting brittle behavior
Fatigue &Fracture of Engineering Materials &Structures, Volume 44, Issue 12, Page 3499-3516, December 2021., 2021 Abstract This paper focuses on numerical the prediction of multiaxial static strength of lattice structures. We analyze a body‐centered cubic cell printed with Selective Laser Melting in AlSi10Mg aluminum alloy. Parent material is experimentally characterized, and the Gurson‐Tveergard‐Needleman (GTN) damage model is calibrated to predict failure in ...

Gradient‐enhanced damage growth modeling of ductile fracture
International Journal for Numerical Methods in Engineering, Volume 122, Issue 20, Page 5676-5691, 30 October 2021., 2021 Abstract We present a gradient‐enhanced damage model for ductile fracture modeling, describing the degraded material response coupled to temperature. Continuum thermodynamics is used to represent components of the energy dissipation as induced by the effective material response, thermal effects, and damage evolution.
