The resistance pressure was the key to solve these problems that long rod projectiles penetrated ceramic targets at high velocity. Based on the twin shear united strength theory and the A-T model, the penetration depth were calculated. But the calculation result didn’t agree with experiment data. So the tension-compression ratio was redefined to apply to the dynamics problems according to the experiment data. And satisfied results were obtained.

The numerical simulation of ballistic multi-hit impact on ceramic/composite armors is very challenging. The damage introduced by the previous hit affects the performance of the armor. In composite backings the damage is often more diffused than for metallic backings. Moreover, different sources of damage can intervene within the composite material. The present work proposes a mesoscopic scale approach to assess these issues. The 2D woven material is modelled with beams elements embedded in volume elements. Each component has its own material constitutive law and its damaging law. This approach allows to better model the damaging of the material, but also to better identify the material parameters from a set of basic experiments.

Hybrid Ceramic

This paper mainly focuses on the investigation of dynamic penetration and damage characteristics of a hybrid ceramic composite armor normally impacted by 12.7 mm armor piercing incendiary projectiles. The hybrid ceramic composite armor was composed of a ceramic cylinder layer, a Ti–6Al–4V plate, an ultrahigh molecular weight polyethylene (UHMWPE) composite layer, and an Al alloy panel. Three different areal densities of composite laminates with 82, 87, and 92 kg/m2 were tested. 3D finite element model of the ceramic composite armor was generated in ABAQUS, and the simulation results were employed to study the damage evolution. The effect of alumina ceramic cylinders layer on the ballistic performance and the failure mechanisms of Ti–6Al–4V and UHMWPE after ballistic impact were examined by experimental and simulative results. According to the numerical and analytical models, an optimal thickness range of Al alloy back panel was found in minimizing areal density of the ceramic composite armor.

Ceramic Composite Armor

Advanced ceramic materials are required to meet increasing high temperature demands of components in advanced propulsion engines for high performance aircraft as well as increasing structural demands in ceramic-composite armor. Monitoring the structural performance of these advanced ceramic materials presents challenges. Recently a new technology, Evisive ScanTM, based on microwave interferometry has been developed that allows condition monitoring. The internationally patented Evisive Scan™ method (1, 2, 3, 4, 5, 6), utilizes microwaves to interrogate dielectric materials. The microwaves are reflected at areas of changing dielectric constant. The reflected energy and the interrogating beam are combined to form an interference pattern which is measured in the transceiver as a signal voltage. The signal voltage is sampled at many positions in the inspection area. This point cloud is displayed as an Evisive Scan™ image, which presents volumetric detail of the inspected part. Over the past two years the technology has been demonstrated on Ceramic Matrix Composites and has shown to be an efficient measurement of porosity and manufacturing defects. The method has also been demonstrated to be applicable to ceramic composite armor made of monolithic ceramic tiles in complex, multilayer structures.
