TL;DR: In this paper, a numerical model was developed to predict the behavior of thin woven laminates under high velocity impacts, which was implemented in a user subroutine to be used with a commercial FE code, taking into account different failure mechanisms.

TL;DR: In this paper, a microstructure model of 3D orthogonal woven fabric (3DOWF) was established and imported into finite element geometrical preprocessor.
Abstract: The ballistic impact damages of 3D orthogonal woven fabric (3DOWF) penetrated under a conically cylindrical rigid projectile were investigated from experimental tests and finite element simulations. A microstructure model of the 3DOWF was established and imported into finite element geometrical preprocessor. In the microstructure model, the architecture of the 3DOWF has the same spatial configurations with that of the real 3DOWF, including the spatial distributions and cross-sections of warp, weft yarns, and Z-yarns. Mechanical parameters of the yarns were obtained from high-strain rate tests which near to the impact loading condition in ballistic tests. The impact damage evolutions of the 3DOWF were simulated with the commercial finite element code ABAQUS/Explicit. From the comparisons of damage morphologies and residual velocities of the projectile after perforation between experimental and finite element simulation, it was found that the simulation can reflect the impact damage precisely. Furthermore, ...

TL;DR: It is important for the trauma surgeon to understand the basic principles of terminal gunshot ballistics and the study of the projectile's effect on striking soft tissue.
Abstract: • It is important for the trauma surgeon to understand the basic principles of terminal gunshot ballistics and the study of the projectile's effect on striking soft tissue. The amount of kinetic energy dissipated to the tissue is directly related to the mass and velocity of the projectile as follows: K = MV 2 /2. Doubling the velocity quadruples the energy, while doubling the mass only doubles the energy. A temporary tissue cavity is produced as the striking projectile compresses the surrounding tissue; the higher the energy release, the more extensive the inapparent compressive damage. The permanent cavity that remains is the result of extrusion of tissue from the pathway of the projectile. The higher the velocity, the higher the likelihood of extensive damage. If the missle expands or fragments within the tissues, more damage will occur. ( Arch Otolaryngol 1983;109:313-318)

TL;DR: In this article, a passive electromagnetically responsive device such as a tuned inductive-capacitive circuit is used to detect a target by stimulating oscillations at the resonant frequency of the circuit by a pulsed electromagnetic field.
Abstract: A projectile is provided having contained therein a passive electromagnetically responsive device such as a tuned inductive-capacitive circuit. The circuit is preferably detected by stimulating oscillations at the resonant frequency of the circuit by a pulsed electromagnetic field. The projectiles are desirably used to enable remote tagging and detection and/or identification of objects including livestock.

TL;DR: In this paper, a model of oblique penetration of a rigid projectile into a thick elastic-plastic target has been developed, which incorporates stress-free boundary conditions at the rear surface of the target.
