- Abstract:
- ABAQUS/Explicit explicit finite element analysis software was used to numerically simulate the lateral impact of solid steel strip under the subcritical velocity of large mass rigid body. The strip constitutive model adopts the JOHNSON-COOK model considering the influence of strain rate and temperature, and the failure mode adopts the shear failure mode of JOHNSON-COOK accumulated damage. The observation of elastic waves verifies the reliability of the simulation. The simulation results observe the discontinuity of impact contact and the inertial swing elongation of the steel plate strip. The neck pulling phenomenon occurs at the edge of the impact contact zone, and the rigid body slips into the span at the same time. The analysis of the simulation results shows that the epitaxial propagation of the plastic deformation of the steel plate strip near the impact zone is carried out by strong plastic intermittent wave.
