Opis:
In this study, the impact performance of layered structures made of aramid/epoxy, S2 glass/epoxy, Dyneema and steel subjected to high velocity impact is presented. All materials were previously examined using proper techniques of strength tests. The procedure allowed determining Young’s moduli, Poisson’s ratio, ultimate compression and tension strength, shear modulus. The ballistic test procedure was based on standards for testing panels and armour plates. For the purpose of ballistic tests, standard 5.56 NATO ammunition (183 g) was used. The aim of presented work was to determine ballistic performance of different structures under bullet impact. During the tests, subsequent time moments were recorded using Phantom V12 high-speed camera. When structure penetration did occur, the residual velocity of bullet was measured using PVM-21 lightscreen. Basing on the results, each material performance was evaluated. This paper reviewed a number of mechanisms that influence the ballistic performance of ballistic textiles. The composites reinforced with continuous fibres (aramid, S2 glass) could effectively absorb the kinematic energy of bullet. The efficiency of energy absorption for each types of material in the order from highest is as follows: polyethylene fibres Dyneema HB50, composite reinforced with S2 glass fibres, composite reinforced with aramid fibres.

Opis:
The paper presents experimental static tests of IED interrogation arm for Shiba special vehicle. The test was performed by Military University of Technology and Military Institute of Engineer Technology. A number of strain gauges and camera markers were placed on the arm to allow recording strains and movements of specific construction points. The arm's motion was recorded using high speed camera. The equipment used were Vishay EA 06 120LZ 120 strain gauges with ESAM Traveller bridge. The sampling rate was 1000 Hz. The test was to pick up maximum design weight, move it to maximum overhang and then drop it on the ground. During the test, signal from gauges and video capture was recorded. The data was then processed using Thema 3D software to obtain markers displacements and angular changes of both arm parts. Afterwards, the test was repeated for different weight. The analysis showed, that maximum stresses in examined construction parts did not exceed yield stress of material. As well as that, in-depth motion analysis of the arm was conducted. Further works are twofold. Firstly, there will be tests concerning arm under dynamic load occurring during normal maintenance During this test only strains in specific construction parts will be recorded. Secondly, numerical model of an arm will be developed and validated using data obtained during both tests. This will help visualize stress distribution in each arm's part.

Opis:
The paper presents experimental test of mine flail structure designed for a prototype of the Shiba special military vehicle. The Shiba vehicle is equipped with such structure to neutralize mine and IED threats which are one of the most harmful weapons used during modern warfare and peacekeeping missions. The experimental test was performed by the Military Institute of Engineer Technology and the Military University of Technology. The test procedure was based on NATO standards. Detonation of 8 kg TNT AT mine under wheel of the prototype was taken into consideration as a case of possible load during mine clearance operation on the battlefield. The test procedure included deformation measurements of selected parts of mine flail structure. During the tests, strain gauges and camera markers were placed on the structure to allow recording of strains and observation of the specific construction point’s movements. The motion was recorded using three high-speed Phantom cameras. Vishay EA-06-120LZ-120 strain gauges with ESAM Traveler bridge with sampling rate 100 kHz were used for strain measurements. The test was performed on military proving ground. As a result, strain versus time plots were obtained. The results were processed using ESAM software. Strain gauges were placed paired in specific structure points. High-speed camera recordings were obtained to visualize the process of structure response. The sequences of selected frames are shown. Pictures of deformed structure are presented.
