| 英文摘要 | In this study, a new damage-effect-involved phenomenological crystal plasticity model is proposed to capture macroscale straining hardening and strain softening behaviors of iron chromium aluminum (FeCrAl) alloys. The constitutive model is described with co-rotational tensors. Damage factor evolves with the effective plastic work calculated by the resolved shear stress and shear strain rate on all slip systems. A stress update algorithm is specially established, and the corresponding self-defined subroutines are incorporated into the finite element analysis via VUMAT in ABAQUS/Explicit. Fast convergence can be achieved with the maximum value of damage factor set very close to 1. The simulated macroscale stress-strain curves can agree well with the experimental ones for various FeCrAl alloys. The yield strengths and ultimate tensile strengths of these alloys can be well captured. The dependence of damage model parameters on the processing conditions, alloy compositions are discussed and analyzed. This work provides a basis for the multiscale simulation research on the mechanical performances of polycrystal alloys. |
