Introduction The process of the ballistic piercing of light composite materials (like bulletproof shields) includes a change in deformation velocity which is significant from the moment of impact to the moment of destruction (piercing the shield).
Hence, in the case of high deformation velocities, the proper modelling of the constitutive compounds of materials becomes a serious problem [1, 2, 3].
The results of this analysis will be used for formulating postulates concerning parametric identification procedures for various structural materials, including composite materials (e.g. aramid etc.).

Structure analysis Crystal structure of materials was determine by XRD technique.
The statistical distribution of values are shown in Figures 4b, 5b and 6b with 10±2 nm, 2.5±0.4 nm and 8±1.7 nm for as synthesized ZnO and ZnO2, and for ZnO obtained by annealing, respectively; the last two materials have narrow size distribution, confirming the material synthesis methodology for both materials are adequately.

The composition of each elements are Fe = 1.02 %, Si = 4.08 %, Ti = 19.44 %, O = 73.43 %, and Cu = 2.03 %, it shows that oxygen elements have the highest percentage because all of the syntesized material are oxide materials, and surface of material dominance by the TiO2 materials.

The first criterion used to differentiate vinegars was the type of raw materials of vinegars.
Three trends can be observed: Vinegars with different raw materials could be classed in different groups, this owing to vinegars made of different materials with different ingredients and contents in the vinegar fermentation modes[36,37,38,39]; Group B, E and F were proximity may be owing to the single type material; Samples with the same raw materials could be classed in the same group.
The classification of the vinegars according to six kinds of materials is absolutely correct.
