“…Applications range from body armor to the protection of mission-critical military and commercial structural components. For overviews, recent applications, models, and case studies see Roylance and Wang [20], Taylor and Vinson [25], Shim et al [21], Shockey et al [22], Johnson et al [11], Tabiei and Jiang [24] Kollegal and Sridharan [13], Simons et al [23] and Walker [27]. A primary current concern is to determine the number of sheets of ballistic fabric shielding needed to stop an incoming projectile.…”

In this paper a simulation technique is developed to estimate the number of ballistic fabric sheets needed to stop an incoming projectile. Such sheets are free of any fortification by a resin. The computational approach is designed so that it can be easily implemented by a wide audience of researchers in the field, without resorting to more involved finite element formulations. This is achieved by taking advantage of the intrinsic characteristics of such fabric structures. Since the deformations of the fabric are (a) finite, (b) nonlinearly inelastic due to progressive fiber degradation and (c) dynamically coupled to the projectile, the system is highly nonlinear. A temporally adaptive, iterative scheme is developed to solve the system. Theoretical issues pertaining to convergence of the algorithm are investigated. Large-scale 3-D numerical examples are then given to illustrate the approach in determining the number of sheets needed to stop a projectile.

“…Since these models neglect or roughly approximate the actual undulated woven geometry, they are ineffective at calculating the out-of-plane and shear moduli. Other methods of predicting plain weave fabric composite material properties include the energy equivalence method (Zhang and Harding, 1990), variational potential energy (Zhong and Van Hoa, 2001), and full-scale discretization using the finite element method (Dasgupta et al, 1996;Dasgupta and Bhandarkar, 1994;Kollegal and Sridharan, 2000a;Kollegal and Sridharan, 2000b;Kollegal and Sridharan, 1998;Sheng and Hoa, 2001;Kuhn and Charalambides, 1998a;Kuhn and Charalambides, 1998b;Aitharaju and Averill, 1999;Kuhn and Charalambides, 1999;Blackketter et al, 1993). These methods are significantly more powerful and comprehensive than CLT, but are also much more complicated and computationally expensive to implement.…”

High-speed impact of electromagnetically sensitive fabric and induced projectile spin

This work deals with the dynamic contact of a rigid body with a deformable electromagnetically sensitive fabric structure, represented by a network model. Of particular interest are the electromagnetically induced forces generated on the fabric, which are proportional to the external electric field (E E X T ) and the velocity crossed with the external magnetic field (v × B E X T ). These forces transmit reactions to the rigid contacting object, which can induce rotational motion. Modeling and simulation of this effect can be useful in ballistic shielding applications, because the rotation of an incoming, ogival, projectile allows it to be more easily impeded. A modular formulation for the deformation of impacted fabric structures, represented by a network model, is developed in this paper, characterized by (1) stretching of interconnected yarn networks, described by simple constitutive relations, including yarn damage, (2) interaction with impacting objects, incorporating contact with friction and (3) electromagnetic sensitivity and actuation, demonstrating how the Lorentz force can be harnessed to break symmetric deformation patterns in order to induce spin onto an incoming object, whether that object is electromagnetically sensitive or not.
