Hot damage evolution in a high strength aluminum alloy during hot forming: a study using the Gurson–Tvergaard–Needleman model

open access: yesJournal of Materials Research and Technology, 2021
The investigation on the formability of 7075-T6 aluminum alloy at elevated temperatures is significant due to its low plasticity at room temperature. Meso-Damage mechanics suggests that the growth and accumulation of micro-voids is an important factor ...

Quantitative Anisotropic Damage Mechanism in a Forged Aluminum Alloy Studied by Synchrotron Tomography and Finite Element Simulations

open access: yesAdvances 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 ...

Parametric study of piercing force and surface quality in elastomer-assisted tube piercing [PDF]

open access: yesScientific Reports
Piercing metal tubes is essential for creating openings in multi-port industrial fittings. Conventional piercing techniques often struggle to provide satisfactory edge quality, leading to challenges such as needing pre-drilling, limitations to circular ...

AA5052-PVC-AA5052 (Al-PVC-Al) Sandwich Sheets Forming Analysis through In-Plane Plane Stretching Tests. [PDF]

open access: yesScientificWorldJournal
Sheet 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.

Numerical Study of Block Tearing Failure in Steel Angles Connected by One Leg [PDF]

open access: yesArchives of Civil Engineering, 2021
Block tearing is a failure mode of steel connections based on rupture of material. In this paper, a numerical model is developed to capture fracture initiation and progression until failure in steel angles connected by one leg using single row of bolts ...

On the predictive capabilities of non‐local models for ductile crack propagation under different levels of stress triaxiality

open access: yesProceedings 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.

Tensile behaviour of welded S700 rectangular hollow section X‐joints

open access: yesce/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 ...
