## Description

- description: "A numerical approach combining cellular automaton and crystal plasticity
    finite element methods was proposed to investigate slip behaviors of additive
    manufactured Ti-6Al-4V material under dwell fatigue condition. Compared with conventional
    polygon-based microstructure models, the proposed method generates microstructures
    that more closely resemble the actual material and allows the simulation to explicitly
    account for the influence of grain shapes on local stress distributions and slip
    system activation. A Burgers orientation relationship based minimum elastic strain
    energy indicator was introduced to determine the α-variant selection during the
    β-to-α phase transformation. A cellular automata code, ExaCA tool was utilized
    to generate a selective\r\nlaser melting fabricated microstructure. The crystal
    plasticity parameters of the model were calibrated based on tensile test results
    of the additive manufactured specimen and subsequently applied to the dwell fatigue
    simulation. The results reveal material hardening arising from accumulated slip
    system activations and show the relationship between load shedding and slip activity,
    which is consistent with our previous findings. This approach overcomes the limitations
    of traditional modeling methods and offers the potential to elucidate the underlying
    fatigue mechanisms of additively manufactured Ti-6Al-4V alloys."
