And 1 1 1 N forces, if only elasticity were present. 3. 3. 2. 4 GPa, respectively. Obviously the elastic limit was exceeded at all these forces so the authors fully realize that those reported average contact stresses are inaccurate; however. it is convenient for the sake of discussion to report those values nonetheless. The 13N force shows the disadvantage of the use ofthe 300 pm diameter indenter to identify yield: the average contact stress was already above 15 GPa. 3 GPa). These ranges of stress are similar to the threshold stress level that Holmquist has inodeled and identified for overcoming dwell .
The two different types of nonoxide materials were based on biomorphic SiSiC, manufactured via the LSI process at DLR. For the oxide materials, two types of alumina tiles, ALOTEC 96SB and ALOTEC 99SB, manufactured by dry pressing and sintering were used. These commercially available tiles are produced in high volumes by ETEC GmbH, Germany, and are successfully used for various lightweight annour applications like body armour or vehicle protection systems. Biomorphic SiSiC ceramics were manufactured either by the use of commercially available medium dense fibre boards (MDF) as green bodies or from wood based composites (WBC), developed at DLR.
Figure 7. Cyclic load-indenter-depth-of-penetrationas a function of peak load in Sic-N with a 300 pm diameter indenter. The six graphs indirectly correspond to the indents shown in Fig. 5 ; however, those images in Fig. 5 are from a single cycle indent sequence. Indent images as a function of peak force for Sic-B, Sic-N heat treated at 2500°C, SIC-SC-lR, Ceralloy 146, and Hexoloy SA are respectively shown in Figs. 8-12. The Sic-B had a similar response to the Sic-N.
