“…2 The primary researches in the field of impact mechanics were focused on the nonlinear dynamic behavior of simple structures subjected to high rate impact load. 3,4 High rate impact load is caused either by an object directly striking the sheet 5 or under the pressure wave created by a water shock tube. 3 Investigating the dynamic response of clamped structures under water-backed condition attracted a great amount of interest.…”

In this paper, the dynamic plastic response of isosceles triangular plates under hydrodynamic loads was investigated experimentally using a drop hammer machine. To do this, a series of experimental tests were carried out on mild steel triangular plates with different thicknesses to bring insight into the effect of geometry and mechanical properties of the plate on the deformation of specimens, which were impacted by a piston-induced pressure wave inside a water tube. The effects of various impact loads originated from different drop hammer standoff distances, and hammer weights concerning variations of deflection of the center of mass were described. The experimental results were presented in terms of deflection of the center of mass of the plates and deflection profiles. The experimental results showed that the plate with lower thickness experienced higher deflection-to-thickness ratio. An empirical model was also proposed based on new dimensionless numbers for triangular plates in order to predict the ratio of deflection of the center of mass to thickness. The dimensionless numbers considered the effects of plate geometry, hydrodynamic applied load, and mechanical properties of materials. Comparison between the experimental results and empirical predictions demonstrated that the suggested model is accurate enough to predict of the response of isosceles triangular plates under hydrodynamic loads.

This paper presents experimental and analytical investigation of the dynamic inelastic response of rectangular metal plates subjected to liquid shock loading. A series of experimental results on fully clamped aluminum alloy and mild steel rectangular plates of different thickness and varying standoff distance of hammer is reported. The effect of varying both shock load and the plate material on the deflection is described. Also, an analytical procedure based on an upper bound solution is used to theoretically study the dynamic behavior of uniform impacted plates. In the present model, effects of strain rate and bending/membrane strain are assumed. The results of the analytical model and the experimental data have good agreement. So, this model can be useful for predicting deformation of rectangular plates under low impact loading.
