Texture evolution and stress formation behaviour during tensile deformation using crystal plasticity finite element method.

This article focuses on the development and application of a three-dimensional crystal plasticity (CP) model to investigate texture evolution and stress distribution in the AA2024 aluminum alloy under uniaxial tensile deformation. After calibrating the model to achieve 98.82% accuracy in simulating stress–strain behavior, the study analyzed five representative grain orientations—Brass, Copper, S, Goss, and Cube—and found that the {111} planes of Brass grains predominantly elongate at about 35.8° relative to the rolling direction, whereas the other orientations exhibit more dispersed, circular texture evolution. Stress simulations indicated that Brass-oriented crystals better alleviate internal stresses during deformation, while Copper-oriented crystals show the highest stress concentration; Cube and Goss orientations display similar intermediate behavior. These findings provide insights into the mechanical response and texture development of AA2024, relevant for optimizing its performance in aerospace and related industries.
