Verification of the linear matching method for limit and shakedown analysis by comparison with experiments [PDF]

, 2013
The Linear Matching Method (LMM), a direct numerical method for determining shakedown and ratchet limits of components, has seen significant development in recent years. Previous verifications of these developments against cyclic nonlinear finite element

Critical Dynamic Stress and Cumulative Plastic Deformation of Calcareous Sand Filler Based on Shakedown Theory

Journal of Marine Science and Engineering, 2023
Calcareous sand is a special marine soil rich in calcium carbonate minerals, characterized by brittle particles. It is, therefore, widely used as a filling material in the construction of islands and reefs.

Low cycle fatigue simulation and fatigue life prediction of multilayer coated surfaces [PDF]

, 2010
This paper focuses on the simulation of low cycle fatigue (LCF) failures in highly loaded coated surfaces subjected to mixed rolling-sliding contact in dry conditions. The development of an advanced finite element (FE) model and creation of a unique user-

Interpretation of intragranular strain fields in high-energy synchrotron X-ray experiments via finite element simulations and analysis of incompatible deformation

Materials & Design, 2021
A finite element framework is developed to resolve the intragranular fields of incompatible deformation generated intrinsically in response to applied deformation, through linear elasticity complemented by the theory of continuous distribution of ...

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

Journal 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

Deformation behavior of K0-consolidated soft clay under traffic load-induced stress paths

Yantu gongcheng xuebao, 2017
Under traffic loads, the magnitudes and directions of the principal stresses applied in the soil elements of soft subgrade change simultaneously. Namely, as the shear stress changes in amplitudes, the principal stress axes continuously rotate.

Formulation of plastic strain distribution derived from long-distance travel of temperature distribution based on residual stress required for elastic shakedown behavior

Mechanical Engineering Journal, 2021
In an experimental study that simulated a fast breeder reactor (FBR) vessel near the coolant surface, it was reported that the long distance travel of temperature distribution causes a new type of thermal ratcheting, even in the absence of primary stress.
