Opis:: The subject undertaken in the study is a glass (fibre) – polyester (matrix) layered composite, of the mixed sequence, composed alternately of laminas reinforced with E-glass plain weave fabric (WR600) and E-glass mat (CSM450). The laminate is manufactured on Polimal 104 polyester matrix. The aim of the study is to determine the options/values of parameters for numerical modelling and simulation of static processes in shell structures made of glass-polyester composites undertaken, in MSC.Marc system, recommended in engineering calculations. The effective elastic and strength constants of homogeneous laminas have been determined experimentally according to the standard procedures. The bending test of composite beams has been conducted experimentally and simulated numerically. Numerical investigations have been focused on selection of options/values of the numerical modelling and simulation parameters. The experimental verification of numerical modelling of the bending test is positive in both the quasi-linear range and in the catastrophic – progressive failure zone.

Opis:: The study presents preliminary experimental range tests of a system for testing protective shields for light armoured vehicles. The shields are designed against HE mines and IEDs up to 10 kg TNT. The system consists of the multiple-use portable range stand, a protected Armox 500T plate and a protective shield. The latter consists of the following main layers: PA11 aluminum, the SCACS hybrid laminate, ALPORAS aluminum foam, and the SCACS hybrid laminate. The layers are connected together with SOUDASEAL chemo-set glue. Overall dimensions of the test stand are ~ 800x800x180 mm, the protected plate has dimensions 650x650x5 mm, and a protective shield is of 450x450x76 mm dimensions. The system rests on a St3 steel plate stiffening the range subsoil. The range stand designed to be resistant up to 10 kg TNT blasts is composed of three appropriately shaped rigid frames connected with six high strength erection bolts. The explosive charge is suspended centrally at 400 mm distance from the top surface of the stand. Two range tests have been performed, i.e.: 1) the protected plate without a protective shield under 2 kg TNT blast shock wave, 2) the protected plate with the protective shield under 2 kg TNT blast shock wave. The effectiveness of the protective shield is assessed via comparing the maximum plastic deflection of the protected plate in both systems. The experimental results have been used to validate the FE model of the system.

Opis:: The paper develops a new methodology of FE modelling and simulation of the SPS and SP systems under 6 kg TNT blast shock wave. SPS code refers to the range stand – protected plate – protective shield ALF system, while PS code refers to the range stand – protected plate system. The multiple – use portable range stand for testing protective shields against blast loadings was developed under Research and Development Project No. O 0062 R00 06. System SPS uses high strength M20 erection bolts to connect the protective shield to the protected plate. In reference to the SPS system, validation explosion test was performed. It has pointed out that the developed methodology of numerical modelling and simulation of SPS and PS systems, using CATIA , HyperMesh, LS-Dyna, and LS-PrePost software, is correct and the ALF protective shield panels have increased blast resistance and high energy – absorption capability
