Armox Advance is a material series that combines exceptional toughness with excellent ballistic properties. They are suitable for use as a protective plate in situations where an explosion is a possibility, such as vehicles of various types. It has excellent hardness and strength, as well as good ballistic characteristics. Regardless, steel is easy to produce. Armox advance is made up of carbon, sulphur, manganese, phosphorus, chromium, nickel, silicon, and boron.
Some of these advantages are negated by the presence of compressive loads on the striking face, which correlates with an increase in adiabatic heating of the plate specimen. When comparing the newly developed ballistic limit diagram to the existing literature, a number of differences emerge, which are explored in light of the flow stress regimes. The Finite Element findings demonstrate excellent correlation with a recently updated version of the analytical Forrestal-Warren model, giving another quick verification technique.
According to the Johnson-Cook model, the aluminium alloy plate and Armox 500T steel plate work in the elastoplastic region in numerical modelling. According to the JH-2 Johnson–Holmquist model, the 99.7% Al 2O3 alumina ceramic operates in the elasto-short range. The calculations are based on massive displacements, large deformations, and potential contact between all of the system’s components. The 8-node 24 DOF hexahedral finite elements with a single integration point were employed in the FE mesh. Ad-hoc erosion of finite elements has been studied using failure criteria.
The crystallographic texture and residual stress in the through-thickness of an ARMOX 500T plate were analysed to better understand the manufacturing approach utilised in the fabrication of High Hardness Armour steel. The authors point out that the hot rolling technique employed in the fabrication of these steels typically results in inhomogeneous through-thickness texture variation, which can affect the armour’s ballistic performance. Two texture components are highlighted by neutron diffraction experiments: a shear texture near the surface and a rolling texture that stretches from 1.5 mm below the surface to the plate’s centreline.
soudaseal 2K chemo set glue is used to link the layers. The components of SCACS hybrid laminate are as follows: SWR800 S-glass plain weave fabric, Tenax HTA40 6K carbon plain weave fabric, Kevlar 49 T 968 aramid plain weave fabric, VE 11-M modified vinyl ester resin (matrix), SWR800 S-glass plain weave fabric, Tenax HTA40 6K carbon plain weave fabric, Kevlar 49 T 968 aramid plain weave fabric The ALFC shield has a total thickness of 90 millimetres. Proof ground tests of a 12.7 mm 13.4 g FSP fragment impact into the ALFC shield – ARMOX 500T steel plate system were conducted at a speed of 715 m/s, and the results were utilised to validate numerical modelling and simulation.
