TL;DR: It is concluded that solder creep is the dominant factor affecting long term reliability of power semiconductor die attachment.

TL;DR: In this paper, a rational approach to the localized necking problem was given by Storen and Rice, which was extended to the arbitrary loading behavior of elastoplastic materials with an arbitrary yield surface by introducing the subloading surface model with the tangential-stress rate effect.

TL;DR: In this paper, a finite strain hyper elasto-plastic constitutive model capable of describing non-linear kinematic hardening as well as nonlinear isotropic hardening is presented.
Abstract: A finite strain hyper elasto-plastic constitutive model capable to describe non-linear kinematic hardening as well as nonlinear isotropic hardening is presented. In addition to the intermediate configuration and in order to model kinematic hardening, an additional configuration is introduced - the center configuration; both configurations are chosen to be isoclinic. The yield condition is formulated in terms of the Mandel stress and a back-stress with a structure similar to the Mandel stress. It is shown that the non-dissipative part of the plastic velocity gradient not governed by the thermodynamical framework and the corresponding quantity associated with the kinematic hardening influence the material behaviour to a large extent when kinematic hardening is present. However, for isotropic elasticity and isotropic hardening plasticity it is shown that the non-dissipative quantities have no influence upon the stress-strain relation. As an example, kinematic hardening von Mises plasticity is considered, which fulfils the plastic incompressibility condition and is independent of the hydrostatic pressure. To evaluate the response and to examine the influence of the non-dissipative quantities, simple shear is considered; no stress oscillations occur. (Less)

TL;DR: Several strength criteria for laminae and laminates are presented and compared numerically in this article, and it is concluded that the von Mises hypothesis is not suitable for composites, instead strength criteria should be derived from Mohr's hypothesis.
Abstract: Several strength criteria for laminae and laminates are presented and compared numerically. It is concluded that the von Mises hypothesis is not suitable for composites, instead strength criteria should be derived from Mohr's hypothesis. In industry mostly laminates are used. It would be desirable if the strength properties could be determined for any arbitrary laminate from those of the laminae included. Since this is spoiled by interaction between the layers, some of these interaction effects are described. In order to become established, a strength criterion has to be verified experimentally. Thus, different techniques for biaxial testing with their characteristic problems are shown.
