摘要A void growth model considering the Bauschinger effect (BE) is proposed for ductile materials sustaining impact loading. Numerical simulations of two high-velocity impact problems are carried out by our newly developed Eulerian programs. The proposed model is tested by a plate impact problem and a qualitative agreement with the experiment is obtained. Then a more complicated problem, a plate impacted by a spherical projectile at a velocity of 6.0 km/s, is simulated. The numerical results are in better accordance with the experimental data when the BE is considered. The proposed model reveals that the BE has an obvious effect on the spall process.
