Abstract

The strengthening mechanisms during mechanical surface treatment methods need to be understood to optimize material surface modification processes. This study combined experimental approaches and physics-based crystal plasticity finite element method to quantify the strengthening contributions of laser-peening-induced microstructural evolutions on the local tensile properties of AA2195-T6 friction stir welded joints. The model predicted the strengthening effects of near-surface compressive residual stresses, work hardening, and crystal morphology evolutions after laser peening application on the joint center. The simulated local joint tensile properties were then inserted into the joint macroscale model to predict the overall modifications in the joint global tensile properties after laser peening. The digital image correlation method was applied with tensile tests to observe local and overall evolutions in joint tensile properties and evaluate modeling results. The crystal plasticity model predicted the enhancements in the joint tensile properties after multiple laser peening applications. As identified by the model, the major laser peening strengthening contribution stemmed from the induced near-surface compressive residual stresses, followed by work hardening and crystal morphology evolutions. Local enhancements in the tensile strength at the joint center and modification in overall joint tensile property homogeneity improved joint mechanical properties after laser peening.
