    Abstract
  • Boundary condition exerts great influence on the failure mode of square plate under intensive loading. In this paper, a series of experiments of clamped square plates with different boundary chamfer radius were performed in the drop hammer impacting machine, in which the drop hammer was specially designed nearly same as the square plate in dimension and the supporting framework could offer various boundary conditions. The results show that: (1) the failure mode of large plastic deformation, one-side tearing and double-side tearing can be observed, and the square plates are more easily damaged under smaller boundary chamfer radius. (2) The boundary chamfer radius has a minor effect on the plate center displacement and deformation profile, but a major influence on the boundary tearing length and crack forming process. (3) The shear effect on the boundary region of clamped square plate would decrease with increasing boundary chamfer radius, and it is more easier for the plate with smaller boundary chamfer radius to get torn under the same intense impulsive loading. The critical failure strain of square plate is among [0.191, 0.241].
