EXPERIMENTAL AND NUMERICAL STUDY OF THE PENETRATION OF TUNGSTEN CARBIDE INTO STEEL TARGETS

摘要：

One of the most challenging aspect of developing a complete material model for brittle materials such as tungsten carbide is to correctly represent the fracture behaviour. Here we examine the fragmentation properties of 7.62 mm tungsten carbide AP projectiles on penetration of a steel target, using experiments with different yaw angles. With a combination of flash X-ray and high speed video, interesting details of the projectile behaviour are experimentally determined. Numerical simulations of the penetration experiments using ANSYS AUTODYN are performed for different fragmentation models. The numerical results are compared with the experiments and discussed. Strain rate dependency is indicated in the compressive strain at fracture.
