Elastic behavior of sandwich panels

1 Choose a cubic single-crystal material (Table 2.4) and use the elastic 

3 Particulate composites with an alumina matrix and zirconia particles 

4 ZrO can form a solid solution with YjOj and the elastic constants are given overpage for various compositions. 

5 The energy of a single bond in ionic crystals is often described by 

Z1O2 composite (fully dense) were found to be above the upper Hashin-Shtrikman bound. Suggest possible explanations. Repeat the discussion for the case in which experimental values were below the lower bound.
