Influence of Moisture on the Shakedown Behavior of Fine Soils for Sustainable Railway Subballast Layers

Infrastructures
This study investigates the influence of moisture on the mechanical behavior of fine soil mixtures from the São Luís region, applied as subballast layers in railway track structures. Two samples were analyzed: a non-lateritic sandy soil (NA’, AM03) and a

Integrated load optimization of elastic‐plastic axisymmetric plates at shakedown

Journal of Civil Engineering and Management, 2010
An elastic‐plastic axisymmetric steel bending plate subjected to a repeated variable load (RVL) is considered. The solution to the load optimization problem at shakedown is complicated because the stress‐strain state of the dissipative systems (e.g.

The Shakedown of Circular Arches for Movable Loads

Engineering Transactions, 1975
The static approach is applied to method analysis of arches under movable loads. The shakedown load value cad be computed if the distribution of residual stresses is known, and limits of passive processes are evaluated in discrete numbers of the cross ...
