- abstract = "Residual stresses are originated during fabrication processes of metallic materials and their study is important to prevent catastrophic failure during service of components. There are two main types of residual stresses, depending on the length scale; macroscopic and microscopic. We present an approach using genetic programming to obtain the micro residual stresses in grains of a quenched cylindrical sample of aluminium alloy AA5083. This alloy has a micro-structure of formed grains with different orientation and stress state. To obtain the micro residual stresses of each grain we estimate the total residual stresses values for every crystallographic orientation using information from electron back-scattered and neutron diffraction experiments. This information includes orientation maps of the normal section to the cylinder axes and the particular orientation and dimensions of every grain. We assume that the micro residual stresses of each grain can be expressed as a function of these variables and use genetic programming to find this expression.",
