Example text

Figure 1: Experimental Set-up The stress state in the sample is triaxial making it non-trivial to calculate the equivalent stress as well as the pressure the specimen is seeing. As it will be shown in the Mathematical Model section and double checked in the Numerical section the expressions to detennine the pressure and the equivalent stress in the specimen are simple and come from the axisymmetrk solution of elasticity problems: -0, + E,, EW(r = b) b2 - a 2 a2 Where a is the inner radius of the sleeve and b the outer radius.

For all cases, the projectile directly hits the ceramics, causes pulverization, and finally large plastic deformation of the back faceplate. The deformations at all stages are quite similar to what have been shown. Similar procedure yields the ballistic limits of the designs without a front faceplate. As shown in Fig. , a 30% mass reduction. Incorporation of honeycomb core brings a bit more ballistic resistance, but still not very 49 significant. These results imply that the front faceplate is not necessary for armor designs involving ceramics; the essentials of metaYceramic armors are the fact that ceramic can deform the projectile and distribute the load over a larger area onto the back faceplate, then the back faceplate consumes the rest of the kinetic energy through plastic bending and stretching.

Crack fannation in ceramics during penetration (3Dcalculations) 0 Elm, 3 1 1 . Ballistic limits of various armor designs in order to obtain the ballistic limits of the proposed armor designs, series of calculations were conducted. For all calculations, the thickness of front faceplate is kept constant at h ~ = l m m ; however the thickness of the back faceplate is varied. For each combination, calculations with various thicknesses of ceramic are performed until a critical thickness (at which the projectile is stopped) is found.
