Corrections in numerical methodology to evaluate plasticity induced crack closure along the thickness.
García-Manrique-Ocaña, José Manuel; Camas-Peña, Daniel; Parrón-Rubio, María Eugenia; González-Herrera, Antonio (Elsevier, 2018-08-15)The influence of the three-dimensional effects of the distribution of the stress intensity factor in the numerical calculation of plasticity-induced crack closure is analysed in this paper. The usual methodology assumes ... -
Fatigue crack propagation analysis in 2024-T351 aluminium alloy using nonlinear parameters
Borges, Micael Frias; López-Crespo, Pablo; Antunes, Fernando Ventura; Moreno-Morales, María Belén; Prates, P. A.; Camas-Peña, Daniel; Neto, Diogo Mariano[et al.] (ELSEVIER, 2021-12)In this work, fatigue crack growth (FCG) in the 2024-T351 aluminium alloy is studied using the plastic CTOD range, Δδp. Experimental tests were performed on 12 mm thick CT specimens in order to obtain FCG rate and in ... -
Numerical modelling of three-dimensional fatigue crack closure: mesh refinement.
Camas-Peña, Daniel; García-Manrique-Ocaña, José Manuel; Moreno-Morales, María Belén; González-Herrera, Antonio (Elsevier, 2018-04-05)Fatigue crack closure has been studied by means of the finite element method for a long time. Most work has been performed considering bi-dimensional models where the numerical methodology has been developed. A great ... -
Numerical modelling of three-dimensional fatigue crack closure: Plastic wake simulation.
Camas-Peña, Daniel; García-Manrique-Ocaña, José Manuel; Pérez-García, Francisca; González-Herrera, Antonio (Elsevier, 2019-10-21)Finite element method has been broadly used to study fatigue crack closure. The simulated plastic wake length is one of the key modelling parameters involved. This paper presents a complete analysis in fatigue crack ... -
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 ...
