FSC uses a non-consumable tool, similar to that used to perform the friction stir welding (FSW) process, to produce continuous and integral channels, with any path, in monolithic aluminium alloys components in a single step. This paper presents the mechanical behaviour of friction stirred channel components in particular the fatigue resistance of the channels analysed. Finite element analyses were performed taking into account the maximum stress values applied in experimental fatigue tests of the aluminium components. The energy release rate for different crack lengths was obtained using the software ABAQUS. The fatigue crack growth curve was established according to the Paris Law, and the crack propagation direction was calculated using the maximum tangential stress (MTS) criterion. During the analysis it was observed that the critical areas are located in the vicinity of the channels corners, as it was observed in the fracture surfaces of the experimental fatigue test results.<\/jats:p>","DOI":"10.1051\/matecconf\/201816521008","type":"journal-article","created":{"date-parts":[[2018,5,25]],"date-time":"2018-05-25T08:28:46Z","timestamp":1527236926000},"page":"21008","source":"Crossref","is-referenced-by-count":1,"title":["Numerical Simulation of the Fatigue Behaviour of a Friction Stirred Channel Aluminium Alloy"],"prefix":"10.1051","volume":"165","author":[{"given":"Catarina","family":"Vidal","sequence":"first","affiliation":[]},{"given":"Ricardo","family":"Baptista","sequence":"additional","affiliation":[]},{"given":"Virg\u00ednia","family":"Infante","sequence":"additional","affiliation":[]}],"member":"250","published-online":{"date-parts":[[2018,5,25]]},"reference":[{"key":"R1","unstructured":"Thomas W.M., Friction stir welding and related friction process characteristics, 7th International Conference Joints in Aluminium, Inalco, TWI, Cambridge, 1998."},{"key":"R2","unstructured":"Thomas W.M., Sylva G., Developments of friction stir welding, ASM Materials Solutions 2003, Conference and Exposition, Pittsburgh, Pennsylvania, USA, 2003."},{"issue":"3\/4","key":"R3","first-page":"4","volume":"49","author":"Thomas","year":"2005","journal-title":"Doc IIW-1664-04, Welding in the World"},{"key":"R4","unstructured":"Thomas W.M., Norris I.M., Staines D.G., Clarke P.J., Horrex N.L., Friction stir welding - variants and process techniques, The First International Conference Joining of Aluminium Structures, Moscow, Russian, 2007."},{"key":"R5","unstructured":"Mishra R.S., Integral channels in metal components and fabrication thereof, Patent no.
