MODELING THE DESTRUCTION OF AN ANISOTROPIC COMPOSITE BARRIER IN INTERACTION WITH SLENDER STRIKERS AT AN ANGLE

A numerical investigation has been made into the interaction of slender (5–20 calibers) steel cylinder strikers with orthotropic compost plates at velocities of up to 2000 m/s. The said interaction has been modeled in a threedimensional formulation within the framework of the phenomenological approach of continuum mechanics using the method of fi nite elements and the proprietary EFES software suite. We have identifi ed the eff ects of orientation of elastic and strength parameters of a composite and a striker angle of attack on the destruction of a plate and the behavior of the striker in the process of its penetration into the plate. It is shown that the existence of an attack angle of the striker in its interaction with the plate results in the loss of the striker stability and exerts a substantiated eff ect on the destruction of the barrier
