Tires are a critical component of military wheeled vehicles and exposed to the threat fragment caused by explosion warhead on battlefield. To study ballistic impact response vehicle tires under fragment, experiments numerical simulations spherical fragments impacting were carried out. The damage mode was analyzed. effects obliquity, tire thickness, mass dynamic tires, as well limit velocity, re...
Textile construction is well known for having a significant effect on the ballistic response of fabrics. One possible mechanism for this effect is the change in yarn-yarn interaction with changes in weave geometry. During an impact event, strain waves propagate through both fill and warp yarns. Energy transfer from warp to fill yarns and fill to warp yarns is a phenomenon that has been largely ...
This paper presents an investigation on energy absorption characteristics of nano-reinforced panels, laminated face sheets and sandwich composites in high velocity ballistic and low velocity punch-shear experiments. The vinyl ester panels were reinforced with 1.25 and 2.5 wt. percent nanoclay and exfoliated graphite platelets. Three different face sheets were manufactured with E-glass, Owens Co...
The impact response of body armor composed of a ceramic plate with an ultrahigh molecular weight polyethylene (UHMWPE) fiber-reinforced composite and layers of UHMWPE fibers shielding a block of ballistic gelatin has been experimentally and numerically analyzed. It is a surrogate model for studying injuries to human torso caused by a bullet striking body protection armor placed on a person. Pho...
