Research— Probabilistic Fabric Modeling to Determine the V0-V100 Response |
|
One of the parameters used to assess the performance of body armor is the V50 velocity defined as “the velocity at which there is a 50% probability of complete penetration”. However a more useful parameter is the V0 velocity, as this indicates the maximum projectile velocity that will be stopped 100% of the time, which is important in human life centric applications. There are many sources of the probabilistic nature of fabric impact, but one of the predominant sources is the statistical yarn strength. For the past decade, most of the computational work involving flexible fabric impact has been deterministic and not probabilistic. We have developed a new framework whereby the entire V0-V100 response of a fabric can be obtained computationally, and a link between the statistical yarn strength and probabilistic fabric impact performance has been established. This reduces the dependence on experimental ballistic impact testing of fabrics which is associated with huge cost. Further, the probabilistic performance of fabrics with different architectures and materials can be compared. Another novel feature of this framework is that the effect of weaving strength degradations and scouring on fabric impact performance can be studied.
