TL;DR: In this paper, the authors provide a formulation and numerical analysis of a two-dimensional plane strain model with multiple discrete voids located ahead of a pre-existing crack tip, and demonstrate that improvements to be expected in fracture toughness by reducing the population of second phase particles responsible for nucleating voids cannot be understood in terms of trends of one mechanism alone.

TL;DR: In this paper, the authors decrit deux exemples de propagation de modes d'instabilite dans des conditions quasi-statiques and quasi-stationnaires: 1) gonflement d'un ballon a partie cylindrique dans lequel un renflement se propage dans the sens de la longueur; 2) affaissement d'a tube sous effet d'une pression externe par suite du flambage.

TL;DR: In this article, the authors studied postbuckling behavior and imperfection sensitivity associated with mode interaction in axially stiffened cylindrical shells under axial compression and proposed a restricted optimization study where the number of stringers is treated as a design parameter, and the range of designs considered includes the optimum design for the perfect shell, where the two modes are simultaneous.

TL;DR: In this article, the authors analyzed a straight-sided delamination buckle with a focus on the effects of substrate compliance, following earlier work by B. Cotterell and Z. Chen.

TL;DR: In this paper, a mechanistic model providing an analytical approximation of undulation growth is presented for realistic cyclic thermal histories, taking into account thickness, lateral growth straining and high temperature yielding of the oxide layer into account.
