2D Simulation of Normal Penetration Using the Unified Strength Theory

A great deal of researches have been conducted on impact and penetration problems. The penetration studies include various experimental, analytical and computational simulations. “Projectile penetration into a semi-infinite target” by an analytical method using the unified strength theory has been described in (Yu et al., 2009). These studies were done by Li JC (2002), Wei XY (2003) and Wang YB (2004) at Xi’an Jiaotong University, Xi’an China. Systematical results can be obtained by using the unified strength theory. The computational simulation of penetration with Yu’s UST (Unified Strength Theory) and AutoDYN for 2D normal penetration, penetration of concrete slabs using UST and SPH (Smoothed Particle Hydrodynamics) methods will be discussed in this chapter. The 3D penetration and perforation will be studied in the next chapter.
