摘要: Abstract This investigation examines the failure of circular plates subjected to impulsive velocities. Experiments are conducted on fully clamped mild steel a uniformly distributed impulse. The strain rate-sensitive exhibit mode I (large ductile deformation), modes II (tensile-tearing and deformation) III (transverse shear) modes. An energy analysis is used test results which enables an balance equation relating input, deformation, tearing disc energies be formulated. input obtained from experimental measurements; deformation predicted by making use final deformed height, shape function rigid-plastic analysis. Good correlation found experiments show good repeatability. threshold velocities for onset given.
