The study of shakedown analysis for Von-Mises half-space
Yantu gongcheng xuebao, 2017 This paper presents shakedown analysis of a half-space obeying Von-Mises criterion under Hertz loads in plane strain model. Based on the static shakedown theorem, a rigorous shakedown solution is established by searching for the best critical residual ...

Structural shakedown: a new methodology for estimating the residual displacements
Journal of Civil Engineering and Management, 2016 A vector of residual forces of the ideally elastic-plastic structure at shakedown is obtained by solving the static analysis problem. A unique distribution of the residual forces is determined if the analysis is based on the minimum complementary ...
