Fretting tests for cyclic plastic law identification: Application to a 1XXX aluminium crossed wire contact

A global–local approach to predict the fretting-fatigue failure of clamped aluminum powerline conductors: From mono-contact crossed wires to full conductor vibrational tests

“…Note that the given cyclic plastic law, estimated from conventional tension-compression law (see section 2.2), is partly representative because it does not take into account the high compressive stress state imposed by the fretting contact. More elaborated strategies including the simulation of fretting scars [32] in the identification procedure need to be considered to extract more representative cyclic plastic law. Another aspect concerns the screening procedure which can be greatly improved by refining the criteria for selecting the most severe contacts.…”
