Inelastic Behavior of a Two-Bar System with Temperature-Dependent Elastic Modulus Under Cyclic Thernical loadings. Such materials are characterized by lack of results concerning the asymptotic behaviors and conditions for shakedown occurrence. This study shows that the considered simple structure is sufficiently complex to experience different periodic long term behaviors as in classical elastopl

A Multiphase Model for Assessing the Overall Yield Strength of Soils Reinforced by Linear Inclusioneen developed in the last years. This contribution is dedicated to the evaluation of the yield strength properties of soils reinforced by linear inclusions by making use of a homogenization procedure, in which the reinforced soil is regarded as a periodic composite, as a first calculation, and using

An Extension of Gurson Model to Ductile Nanoporous Media,scale. For interface stresses obeying a von Mises criterion, we derive closed-form expressions of the parametric equations defining the yield surface. The magnitude of the interface effect is proved to be controlled by a non dimensional parameter depending on the voids characteristic size. It is obs

Limit Analysis and Conic Programming for Gurson-Type Spheroid Problems,omputation led to a macroscopic yield function of the “Porous von?Mises”-type materials. Several extensions have been further proposed in the literature, such as those accounting for void shape effects by Gologanu et al. (J.?Eng. Mater.

Interior-Point Method for Lower Bound Shakedown Analysis of von Mises-Type Materials,alysis is presented for von Mises-type materials. The formulation is generalized for the case of arbitrary finite numbers of loading cases. Numerical details of the algorithm are given and the described methodology is illustrated by a numerical example.

An Extension of Gurson Model to Ductile Nanoporous Media, The magnitude of the interface effect is proved to be controlled by a non dimensional parameter depending on the voids characteristic size. It is observed that nanoporous materials can be made more strengthened than non-porous counterparts.
