TL;DR: In this paper, a series of transient nonlinear dynamics finite-element analyses was carried out in order to investigate the role of the following two important sub-yarn phenomena on the penetration resistance of Kevlar® KM2 fabric: (a) fiber transverse properties including nonlinear elastic and plastic response and (b) fiber-fiber friction within the context of stochastically distributed fiber axial strength.

TL;DR: In this article, the authors developed a three-step approach to determine the optimal tool design and the optimal FSW process parameters which result in maximal productivity of the joining process and the highest quality of the weld.

TL;DR: In this paper, a three-step FSW-joint fatigue strength/life statistical analysis procedure is proposed, in which the type of the most appropriate probability distribution function is identified within the first step, along with their confidence limits, and a procedure is developed for assessment of the statistical significance of the effect of the FSW process parameters and fatigue specimen surface conditions.

TL;DR: In this paper, a multi-prong approach is proposed to address concurrently and interactively all aspects associated with the components/vehicle-underbody design, fabrication, and testing.

TL;DR: In this article, a two-level material homogenization procedure is proposed and utilized to help manage computational cost and computer storage requirements for computational engineering analyses (CEA) for FSW joints.
