Time resolved engineering metal penetration models
conference paper
Current tools describing behavior of ballistic materials under impact seem to be less suitable to assist armor developers in their efforts. They are insufficiently detailed or need comprehensive material properties and material failure description, unavailable in the initial stages of the development of new solutions. Therefore TNO is building a series of calculation tools, capturing the majority of the energy absorption processes during projectile penetration of materials. These tools must finally cover the main ballistic materials (metals, fiber materials and ceramics) with their various failure mechanisms.
In this work, two failure mechanisms for the ballistic behavior of metals are described. The “ductile hole growth” mechanism for relatively thick material and “bulging” for thin sheets are described by a series of simple energy conservation. The thinking process generated by the development and use of these tools, supports armour engineers to create new solutions for projectile
defeat.
