Sapphire and magnesium spinel are two commonly used transparent armor materials. Although it is commonly believed that better mechanical properties often result in better field performance, the ballistic performance of spinel is reported to be superior to sapphire despite its inferior mechanical properties. The above discrepancy has been rationalized on the basis of mechanisms of deformation during impact loading. After reviewing the reported ballistic performance results on spinel and sapphire… CONTINUE READING
