This article presents an analysis of the effectiveness of available numerical techniques in mapping the characteristic behavior of ballistic ceramics under projectile impact conditions. As part of the work, the ballistic tests were performed on the layered ceramic/steel composite armor and tested with the 7.62 × 39 mm, armor-piercing incendiary (API) BZ projectile. The experimental tests were then mapped using computer simulations. In numerical analyses, four different techniques were used to describe cubic ceramic tiles Al2O3 placed on the ARMOX 500T steel backing plate, i.e.,: the Finite Element Method without Erosion (FEM), Finite Element with erosion (FEM + Erosion), Smoothed Particles Hydrodynamics (SPH) and a hybrid method that converts finite elements to SPH particles after exceeding the defined failure criteria (FEM to SPH conversion). The effectiveness of the individual methods was compared in terms of quality (mapping of characteristic phenomena occurring during the penetration process), quantity (bulge height of the backing plate) and time needed to complete the calculations. On the basis of the results of the experiments and numerical simulations, it was noticed that the most accurate reproduction of the phenomenon of ballistic impact of AP projectiles on ceramic/steel composite armor can be obtained by using a hybrid method, incorporating the conversion of finite elements into SPH particles. This method should be used in cases where accuracy of the results is more important than the time required to complete the calculations. In other situations where the purpose of the calculation is not to determine, for example, the exact value of penetration depth but only to observe a certain trend, the FEM method with defined erosion criteria (variant 2), which is more than 10 times faster, can be successfully used.

“…To fully comprehend the role and involvement of composite materials in construction [1], a thorough understanding of the component materials themselves, as well as the numerous ways in which they can be analysed, is required. In most of its common form, a composite indicator [2] is made up of at least two elements that interact together to provide material qualities that are distinct from those of the individual constituents. In applications, many of the composites are made up of a huge amount of stuf (the "matrix") and some form of supplements, which are added to boost the matrix's frmness and rigidity.…”

The phenomenon of separation into constituent layers connecting the core and laminate of a composite sandwich complex is a vital complication that leads to early failure of such material. The direction of the sandwich construction's exfoliation rigidity is increased between interlaminar low fiber augmentation. The bioinspired technique of hybrid material layers was used on an aluminium face sheet with an interlayer composition of PET foam core and glass fabric of a material that appears to have greater potential as a flimsy substitute for materials currently used in automotive, aeronautical, and marine applications. This examination seeks to develop the making of such material along the retardation in fibre supplements. Fibre bridging has been recognized as an important appliance in the progress of this operating procedure. Consequently, this method points to promoting the event of fibre bridging by differing aggregates, including the mass and extent of augmented fibres and the quantity of epoxy resin applied. A few advancements were made to the production methods, and though the outcomes for the resisting ability of specimens were found to be indecisive, it was found that the layer separation hardness had even improved. This was confirmed through the operation of scanning electron microscopy and also predicted the mechanically peeled material surfaces which identified the adhesive strength variations with respect to the face sheet surface modified with the sand blasting process. The analysis also revealed the need for further research into optimizing the attachment between aluminium sheet and pet foam and glass fabric based hybrid sandwich panels.

“…8,9 Inspired by these biologic materials, the layered advanced composites have been developed and proved to be effective in optimizing their inherent brittleness. [10][11][12] For instance, Ben et al 13 applied the Florentine mechanical model to advanced ceramic composites, indicating that an appropriate density arrangement of layers would improve the impact resistance. Pogorelov et al 14 reported the bioinspired ceramic-polymer composite achieved excellent toughness performance, which was nearly two times higher than conch-shell, by only adding up to 6.0 vol% of the polymer.…”

Ceramic materials with high strength, toughness, and excellent impact resistance are urgently required for many structural applications, but these mechanical properties are difficult to achieve in traditional ceramic tiles due to their inherent brittleness. Inspired by the specific structure of shells, the multilayered ceramic tile/Kevlar fabric composite with a bio‐inspired shell structure was successfully fabricated via a surface hydroxylation followed by simple hot press process. It is found that the composites have representative step‐like fracture behaviors rather than brittle fracture, which has been proven to possess a better ability of mechanical performance and noncatastrophic failure behavior compared to same‐thickness ceramic tile. Specifically, the bending strength, fracture toughness, and fracture work of the composite with a 15‐tier structure come to 836.5 ± 12.5 MPa, 14.6 ± .2 MPa·m1/2, and 7228.8 ± 108.4 J·m1/2, which are even better than those of reported advanced materials. Such fracture‐resistant behaviors are correspondent to the strengthening effects of the crack deflection, interfacial debonding, and fiber pull out, accompanied by bio‐inspired structure and appropriate bonding state between brittle or ductile layers. This resin or fabric content can be used as well as the slip systems to transfer the internal stress in time to consume more fracture energy per unit length and prevent risky brittle fracture, while carrying loads. We expect these findings to provide vital guidance for promoting the applications of traditional ceramics in bio‐inspired high‐performance composites for actual ceramic manufacturers.
