On the Conditions to Prevent Plastic Shakedown of Structures: Part II—The Plastic Shakedown Limit Load

Journal of Applied Mechanics, 1993
Following the results of a companion paper, the concept of plastic shakedown limit load is introduced for an elastic-perfectly plastic material structure subjected to combined cyclic (mechanical and/or kinematical) loads and steady (mechanical) load. Static and kinematic approaches are available for the computation of this load, in perfect analogy with

On the dynamic shakedown stability

Meccanica, 1980
Starting from a Benvenuto's sufficient stability Criterion, in the elastic-plastic range, on the load paths which will systematically exclude elastic returns in the actual state, and adopting a suitable incremental formulation of the Ceradini's theorem on the dynamic shakedown, the dynamic shakedown stability property may be proven, if the comparison ...

On Optimum Shakedown Design

1975
During recent years a considerable progress has been made in methods of minimum-weight design of structures. This is due to the progress in mathematical optimization methods as well as to development of more efficient computer facilities. The most impressive are results obtained in elastic design of multiple bar trusses with constraints of various ...

Shakedown of Steel Plates

Journal of Applied Mechanics, 1971
Standard mathematical programming techniques are used for obtaining the shakedown load and stochastic shakedown load of a simply supported axisymmetric plate subjected to uniform pressure. The yield criteria of Tresca, von Mises, and Hill are all invoked.

Shakedown of Rail Corrugations

1995
A model of the elastic-plastic behaviour of a rail under moving and cyclically changing loads is proposed. Simple analytical expressions enable us to estimate the changes of the limit shear stress and residual stresses under the running rail surface after repeated passages of a wheel. It is shown that magnitudes of local hardening and residual stresses

Shakedown of porous materials

Adaptation plastique des matériaux poreux Cette thèse est consacrée à la détermination des états limites de l'adaptation des matériaux ductiles poreux sur la base du théorème de Melan et en considérant le modèle de la sphère creuse. Dans un premier temps, nous proposons le critère analytique macroscopique d'adaptation avec la matrice de
