Biological structures possess excellent damage tolerance, which makes them attractive for ballistic protection applications.This paper develops a finite element modelling framework to investigate the performance of several biological structures that are most relevant for ballistic airtek bags protection, including nacre, conch, fish scales, and cru
The purpose of this study was to improve our understanding of the effect of macro/micro texture on dwell fatigue properties.The Ti-6Al-4V forged bar with highly oriented texture and fine equiaxed microstructure was used.Dwell fatigue, cyclic fatigue and creep tests were conducted at room temperature by using specimens taken in the longitudinal (L)
We study the structure of the rest points of signaling games and their dynamic behavior under selection-mutation dynamics by taking the case of three signals as our canonical example.Many rest points of the replicator dynamics of signaling games are not isolated and, therefore, not robust under perturbations.However, fendi wide belt some of them at
