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 ... -
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 ...
