“…7 for the rnaxlmum permanent transverse displacements of fully clamped square steel plates struck by a mass at the centre. It is evident that the theoretical analysis given by Eqn (13), and by Eqn (13) with coreplaced by 0.61800, bound all of the experimental data. The ratios y and E, are much larger than the one for all of the test results in Fig.…”

This paper examines the response of circular and square plates stluck by a rigid mass at the plate centre with a sufficient initial kinetic energy to produce large inelastic deformations. A simpliiicd analysis, which retains finite-deflection effects and assumes that the plates are made of a rigid, perfectly plastic material, provides a relatively simple theoretical solution for the maximum permanent Inusvet:;: displacement and the response duration. It transpires that the theoretical predictions give reasonable agreement with the maximum v e n t transverse displacements recorded in several experimental studies on fully clamped, circular and square ductile metal plates. The final theoretical expressions for the behaviour are easy to use and ideal for preliminary design purposes and would be sufficiently accurate for final designs in some applications.

“…One of the advantages for using the damage number to predict such kind of failure is that it is conveniently used for dissimilar material modeling. [4] conducted an experimental investigation into the dynamic plastic response and failure of strain-rate-sensitive mild-steel beams due to concentrated impact loads, they found that the beams were dominated by shear failures. Jouri and Jones [5] have found experimentally that the transverse shear severance of beams in double shear loading occurs at a shear displacement which is much smaller than the beam thickness.…”

It is proved that Johnson's damage number is the sole similarity parameter for dynamic plastic shear failure of structures loaded impulsively, therefore, dynamic plastic shear failure can be understood when damage number reaches a critical value. It is suggested that the damage number be generally used to predict the dynamic plastic shear failure of structures under various kinds of dynamic loads (impulsive loading, rectangular pressure pulse, exponential pressure pulse, etc.,). One of the advantages for using the damage number to predict such kind of failure is that it is conveniently used for dissimilar material modeling. carried out an approximate theoretical study of this problem for predicting the onset of these three failure modes. Duffey [7] found that hard-point shear failure in cylindrical shells is adequately predicted by the theory for shear failure in beams, by studying two loading cases (i.e. rectangular pressure pulse and exponential pressure pulse). Zhao et al. found that consideration of the influence of rotatory inertia and the presence of crack increases the initial kinetic energy required to cause dynamic plastic shear failure [8,9]. 349 Vorhersage des dynamisch-plasfischen
