Abstract:

A model for the deformation of multi-layer metallic laminate targets during ballistic impact is described. The model divides the process into a stage of plug acceleration followed by dishing of the rear of the target, and allows for the effects of variable interlamellar bend strength. A computational procedure is described, as well as the mechanical test procedures to generate the input data for the program. Examples of the application of the model are described to illustrate the interpretation of results, the limitations of the model, and the use of the model is parametric studies for laminate design. The computer program is listed with typical input and output data. Keywords Australia.
