Using evolutionary algorithms to determine the residual stress profile across welds of age-hardenable aluminum alloys
DOI: 10.1016/j.asoc.2015.11.004 This paper presents an evolutionary based method to obtain the un-stressed lattice spacing, d0, required to calculate the residual stress profile across a weld of an age-hardenable aluminum alloy, AA2024. Due to the age-hardening nature of this alloy, the d0 value depends on the heat treatment. In the case of welds, the heat treatment imposed by the…
