Reliability-based design optimization of trusses under dynamic shakedown constraints
, 2019 A reliability-based design optimization problem under dynamic shakedown constraints for elastic perfectly plastic truss structures subjected to stochastic wind actions is presented. The simultaneous presence of quasi-static (cyclic) thermal loads is also

Particle breakage and shakedown behavior of granular material under cyclic loading conditions
Abstract The geomechanical performance of railway ballast is critical to the long-term stability of heavy-haul track systems. Limestone aggregates are often disregarded for such applications due to their susceptibility to particle breakage and permanent deformation.

Dynamic shakedown of structures with variable appended masses and subjected to repeated excitations
, 1996 Elastic shakedown for discrete, or finite-element discretized, structures subjected to combinations of static and time-variable loads is addressed in the hypothesis of elastic-perfectly plastic material behavior.

True stress and shakedown analysis of pressure vessel under repeated internal pressure
, 2016 This study aims to investigate the true stress and the plastic shakedown behavior of a cyclically loaded pressure vessel. To serve this study, an experimental platform has been built up, which comprised of a self-made thin-wall ...

Estimating the Shakedown Limit for Granular Materials Under Cyclic Loading
The influence of cyclic loading on the deformation response of granular materials is usually described using the shakedown concept. The shakedown response can be characterized into different shakedown regions such as plastic shakedown, plastic creep and ...
