Abstract

The present work deals with the simulation of rolled Ti 6Al 4V plates with three different microstructures, which are tested for their protective effect against projectiles of caliber 7.62x51 [mm]. The aim is to evaluate and compare the protective effect and the mechanical properties of the individual plates. Another aim of this thesis is to use FEM simulation to evaluate the behavior of the heat-treated titanium plates under fire. By using the simulation it should be possible to save time and costs for ballistic tests in the future. The materials were provided by voestalpine BÖHLER Bleche GmbH & Co KG and were heat treated in the course of a dissertation project at the Chair of Physical Metallurgy and Metallic Materials. Furthermore, split Hopkinson bar test were carried out to determine the material parameters. The material deformation is modeled with the finite element program Abaqus by using a Johnson-Cook material model. The simulation is based on the one hand on data from the literature, and on the other hand on calculated material parameters. The simulation results are discussed by comparing them with the practical impact tests carried out.
