Abstract

The implementation of mathematical models of ballistic impact on textile structures revealed some computational problems, arising from the complex wave structure of transversal impact on an orthotropic plate, and also from an empirical nature of deformation rapture criteria. The dependence of modelling results on computational options is discussed. A comparison between one- dimensional, two-dimensional isothropic (circular symmetry) and two- dimensional orthotropic impact problems is given. 1 Introduction There was a good deal of work done in recent years to develop methods for the mathematical simulation of the high-velocity impact on textile struc- tures (see V.P.W.Shim et al. [1] for further references). In previous publi- cations (Lomov [2,3,4]) the author has proposed a model which introduces issue
