This paper presents the results of an experimental and numerical study of the perforation of Armox 500T armoured steel.The plate perforation sten jacket m was performed with a pneumatic gun using three types of penetrators.Sharp, spherical and blunt penetrators were used.The use of different geometries of penetrators causes the process of perforation and destruction of plates in a different state of stress and strain, which leads to the appearance of three basic modes of failure.

Numerical analyses of the perforation process have been carried out using the Ls-Dyna computational code with an advanced constitutive model of the material and the integrated failure model.The obtained experimental and numerical results were analysed and compared.The failure popularfilm.blog shape, the level of plastic deformation and the parameters of stress and strain state were analysed.
