Ballistic Penetration and Perforation of Steel Plates Tore Børvik (2000)
This document has been recommended to us by our supervisor as a good first read. It provided us with an in depth introduction of the terminology of ballistics. We will use the paper as a reference throughout this year. What is more the thesis consists of 8 parts which are small research projects themselves. They consider – experimental set-up used ballistic penetration of steel plates, computational model of viscoplasticity and ductile damage for projectile impact, observation on shear plug formation, numerical simulation of plugging failure, effect of projectile nose shape in structural impact and effect of target thickness on penetration.
Engineering models of ballistic perforation at high velocities S. R. Bodner (1983)
This report is based on a research program funded by the US Army Contracting Agency and consists of two documents. The first deals with the development of a 5 stage engineering model of the ballistic perforation process and the second one explains a series of experiments with RHA plates. The 5 stage model provides us with in depth knowledge of the ballistic perforation process. The model includes the following continuously coupled but distinct stages: dynamic plastic penetration, bulge formation, bulge advancement, plug formation and exit and projectile exit. The experiments considered only metal plates as target material. This is not surprising as most of the existing research is based on metals. However the results of the experiments will be used as a benchmark for our computational model.
Ballistic Impact: Recent Advances in Analytical Modelling of Plate Penetration Dynamics – A Review G.Ben-Dor, A. Dubinsky, T.Elperin (2005)
A particularly useful document as it summarises a vast amount of research done in the analytical analysis of ballistic impact. It is a relatively recent paper compared to most of the work that is available to us. The paper separates analytical models in 3 main classes according to the mathematical description - localised interaction approach, cavity expansion approximations and Lambert-Jonas approximation. Analytical models provide relevant data on simple models only. The reason for this is the limited scope of factors included. However we could use them in our initial model tests – they would provide a good starting point of the data validation process.
Simulation of ballistic impacts on armoured civil vehicles B.Adams
This is a Master’s thesis and this is the document closest to what we will produce in terms of format. The document will be thoroughly researched to identify good and bad examples of a thesis work. We will use those to improve the quality of our project. A similar research approach will also be used – set up initial conditions, do an analytical analysis, simulate a FEM model and verify all of these with existing experimental data.
Composite structures under ballistic impact N. K. Naik, P. Shrirao (2004)
This paper presents an analytical model for composite structures under ballistic impact based only on dynamic mechanical and fracture properties of the target material. The paper will be useful at a later stage of the project where we decide to take different research paths. Composite materials were discussed at an early meeting with the supervisor as a possible research path for one of us.
