TL;DR: In this paper, an analytical study of the dynamic growth of microvoids is presented, with the help of a numerical study of void growth relationships derived; the conclusion is that both material viscosity and strain hardening may have an important influence on the tensile strength of ductile materials at high strain rates.

TL;DR: In this article, a two-dimensional axisymmetric numerical analysis of the normal impact problem is performed, where the macroscopic material behavior in the zone of finely pulverized ceramic ahead of the penetrator is modelled by means of a constitutive model taking into account internal friction and volumetric expansion.

TL;DR: In this article, experimental results of a number of tribological tests carried out on aramid woven fabrics are presented in order to investigate the friction and wear phenomena of the fabrics.

TL;DR: In this paper, the authors describe the results of experiments in which 7.62 NATO projectiles impacted on ceramic faced composite armours backed by a fibrous armour, and the design of the armours was based on an energy absorption model proposed by Hetherington and Rajagopalan.

TL;DR: In this article, an analytical study of the dynamic plastic growth of microvoids under the combined action of hydrostatic and deviatoric stresses is presented, with the help of a numerical analysis of the void growth relationship derived, and applied to the case of spall fracture.
