TL;DR: In this article, the authors investigate the possibilities of getting information on the initial yield stress Y from nano-indentation experiments with sharp indenters, using two expanding cavity models (ECM) described in the literature, one for elastic-perfectly plastic and one for power law work hardening materials.
Abstract: The aim of this paper is to investigate the possibilities of getting information on the initial yield stress Y from nano-indentation experiments with sharp indenters. Berkovich indenters have been used for the experiments and the data evaluation was performed by using two expanding cavity models (ECM) described in the literature, one for elastic-perfectly plastic, and one for power law work hardening materials. To characterize the ECMs, finite element simulations with extensive material parameter variations together with substantial experimental data are used. As a first result, the possibilities of determining Y using the introduced ECMs can be shown for the simulated materials (Fig. 3) and the presented selection of real specimens. Furthermore, the restriction of the ECMs to materials where the yield behavior obeys the von Mises yield criteria is discussed. In doing so it is shown that the indentation work, which can be determined directly from the indentation force–displacement curves, represents a useful quantity to assess the applicability of an ECM to a particular material.

TL;DR: In this article, a kinematic hardening model applicable to finite strains is presented, which is based on the residual stresses that evolve due to different obstacles that are present in a polycrystalline material, such as grain boundaries, cross slips, etc.

TL;DR: In this article, a structural weight comparison between a new concept wing design, called a "Joined Wing," and a reference conventional wing-plus-horizontal tail (Boeing 727) was made.
Abstract: A structural weight comparison was made between a new concept wing design, called a "Joined Wing," and a reference conventional wing-plus-horizontal tail (Boeing 727). The joined-wing analysis includes two cases that differ only in minimum gage skin thickness. The comparison was accomplished by constructing finite-element computer models of each wing configuration, analyzing each for optimum skin thickness, then determining the structural weight of each wing. The optimizations were based on a fully stressed design concept using a Von Mises criterion for maximum allowable stress. The joined wing was found to be lighter by 12-22%.
