Accumulation of progressing deformations of the threaded joints M16 under low cyclic bending/Progresuojantis deformacijų kaupimasis mažaciklio lenkimo veikiamose srieginėse jungtyse M16

open access: yesJournal of Civil Engineering and Management, 1998
In some threaded joints, over a period of operation the conditions of compression are created, most likely owing to the prestress and bending caused by external loads. For elements in the cross-section in which the stresses are distributed unevenly, some

Shakedown and limit analysis of periodic composites [PDF]

open access: yesPAMM, 2009
AbstractThe optimization of fiber distribution is analyzed in order to improve the strength performance of metal‐matrix composite material, which is submitted to two variable independent loads by coupling homogenization and shakedown theories. Numerical Direct Methods are applied to acquire the shakedown domain of three‐dimensional heterogeneous ...

Memory of Stress History in Single and Two Surface Plasticity for Granular Soils

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 2, Page 597-612, 10 February 2026.
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

Influence of Asphalt Emulsion Stabilization on Pavement Structural Behavior and Life Cycle Assessment (LCA)

open access: yesAdvances in Civil Engineering, Volume 2026, Issue 1, 2026.
Assessing pavement sustainability requires jointly evaluating structural performance and environmental impacts, yet these dimensions are often analyzed separately. This study proposes an integrated framework combining mechanistic–empirical pavement design and life cycle assessment (LCA) to quantify the structural–environmental trade‐off associated with

Incremental elastic-plastic analysis of a continuous steel beam with shakedown

open access: yesRUDN Journal of Engineering Research, 2014
An algorithm of the incremental elastic-plastic analysis of a continuous steel beam is presented in this paper. An elastic limit state has been determined, and formation of plastic hinges and collapse mechanism has been investigated.

One Some Basic Problems of the Theory of Shakedown

open access: yesEngineering Transactions, 1977
The paper presents the observation that discrete structures of the global condition of shakedown does not need necessarily require that the shakedown condition of each element should be satisfied. A simple example illustrates the thesis.
