Optimization of two-component composite armor against ballistic impact
Using Florence's model we determined an optimal design of a two-component ceramic-faced lightweight armor against normal ballistic impact. The solution is found in a closed form that allowed us to determine the thicknesses of the plates in the optimal armor as functions of the specified areal density of the armor, parameters determining the material properties of the armor's components and characteristics of the impactor.
On the optimisation of two-component plates against ballistic impact
Abstract Based on an existing model, a design criterion has been developed which gives the optimum performance of two-component ceramic armour under a given total thickness. With the threat defined, the approximate thickness ratio of the two plates can be calculated easily. Test findings show reasonable agreement with the predicted values. The criterion provides a quick and simple tool for armour-design engineers to use to evalute the possibilities of two-component ceramic armour.
The role of mean maximum pressure in specifying cross-country mobility for armoured fighting vehicle design☆
Abstract This paper examines the relationship between a military vehicle's mobility and its survivability. The theoretical model governing this relationship is based on a series of steps, each of which is critically examined. The tactical role of the vehicle is translated into a mobility requirement stated in terms of the percentage of ground to be trafficable in specified areas. The assessment of soil strength is achieved using the cone index, the statistical handling of which is described. The link between Vehicle Cone Index and Rowland's Mean Maximum Pressure (MMP) is discussed, as is its role as an indicator of vehicle mobility. Vehicle and armour weight follow directly from Rowland's MMP, leading to an assessment of survivability. Examples are given of the effects of varying the mobility requirement, the threat level and the armour type on the ultimate survivability of the vehicle.
