The Influence of Tool Geometry on the Mechanical Properties and the Microstructure of AA6061-T6 Aluminum Alloy Friction Stir Spot Welding.
Alkhafaji, Amir; Camas-Peña, Daniel
; López-Crespo, Pablo; Al-Asadi, Hayder (MDPI, 2023-06-01)
In this work, the influence of the tool geometry on friction stir spot welding (FSSW) was studied on sheets made of AA6061-T6 aluminum alloy. Four different AISI H13 tools with simple cylindrical and conical pin profiles ... -
Three-dimensional fatigue crack closure numerical modelling: Crack growth scheme
González-Herrera, Antonio; Camas-Peña, Daniel; García-Manrique-Ocaña, José Manuel; Antunes, Fernando Ventura (Elsevier, 2020)
Numerical models based on finite element method have been employed to analyse the plasticity induced crack closure phenomenon for a long time. These numerical analyses require the development of a plastic wake. During ... -
Three-dimensional numerical study of thickness effect on plastic CTOD and monotonic plastic zone in an aluminium CT specimen
Camas-Peña, Daniel; Branco, Ricardo; Antunes, Fernando Ventura; Neto, Diogo Mariano (Elsevier, 2023-10-10)
This work is a numerical study of CT specimens with straight cracks and different thickness values submitted to different load levels, which aims to analyse the shape and dimension variations of the monotonic yielded area ... -
Through thickness evolution of crack tip plasticity
Camas-Peña, Daniel; López-Crespo, Pablo; Antunes, Fernando Ventura; Yates, John R. (2017-07-19)
Experimental methods to measure fracture mechanics parameters tend to provide information from or about the surface of cracked components. However, information about the interior of the component is key to understanding ...
