| Abstract | Spalling is a typical tensile failure that results from the coupling evolution of microstructure and microdamage under high strain-rate loading. To understand the spalling damage behavior of polycrystalline materials at mesoscale, this paper develops a spalling model by integrating the crystal plasticity theory and the microvoid growth theory. The model is implemented in ABAQUS simulation via the VUMAT subroutine to simulate a planar impact process of copper, and the results are compared with experimental data. Due to the inhomogeneity of crystal plastic slip, the local stress fluctuates severely near the grain boundary. Therefore, without introducing the fluctuation in the threshold stress for microdamage evolution, this model can simulate the heterogeneous feature of microvoid nucleation, growth, and coalescence in materials. The results show that microvoids tend to nucleate at 25 degrees-50 degrees misorientation angle grain boundaries, which undergo a high probability of stress fluctuation. |
