摘要：

The shrink-fit technique has been used to study the effect of prestress and confinement on ceramic materials. Calculation of prestress in ceramics tile wrapped by metal and optimized design for the composite are presented. Alumina tile confined with aluminum alloy, which was in a state of triaxial compression, was chosen as the tat-get in impact tests to investigate the impact resistance of prestressed ceramics. The results from two types of impact tests indicate that both impact resistance and armor-piercing resistance are greatly enhanced due to the presence of prestress and compact confinements, and that triaxial prestress is much better than biaxial prestress for enhancing the impact resistance of ceramics.
