On the shakedown analysis of welded pipes [PDF]
This paper presents the shakedown analysis of welded pipes subjected to a constant internal pressure and a varying thermal load. The Linear Matching Method (LMM) is applied to investigate the upper and lower bound shakedown limits of the pipes. Individual effects of i) geometry of weld metal, ii) ratio of inner radius to wall thickness and iii) all ...

Shakedown analysis of red mudstone fill material with different water contents
Understanding the shakedown behavior of fill material is paramount to estimate the deformation stability of railway subgrade. Especially for red mudstone fill material (RMF), the noticeable overestimation of bearing capacity would be encountered if the ...

RSDM: A Powerful Direct Method to Predict the Asymptotic Cyclic Behavior of Elastoplastic Structures
Mechanical engineering structures and structural components are often subjected to cyclic thermomechanical loading which stresses their material beyond its elastic limits well inside the inelastic regime.

Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model
ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

Self‐Expanding Cardiovascular Stents: Potentials and Challenges of Shape Memory Biomaterials
ABSTRACT Cardiovascular diseases affect a large portion of the global population and remain leading causes of morbidity and mortality. Endovascular stenting, a minimally invasive procedure, enables the insertion and deployment of stents to restore arterial patency without open surgery.

Shakedown Analysis of Layered Continuum [PDF]
Failure of structures associated with repeated moving surface loads are typically caused by gradual deterioration rather than sudden collapse. This type of failure behavior is mostly due to the accumulation of plastic strains under repeated loadings. They are different from the solution of most stability problems under simple loading programs.

Shakedown Analysis of a Composite Cylinder With a Cross-Hole [PDF]
In this study, both the lower and upper bound shakedown limits of a closed-end composite cylinder with or without a cross-hole subject to constant internal pressure and a cyclic thermal gradient are calculated by the linear matching method. Convergence for the upper and lower bound shakedown limits of the composite cylinders is sought and shakedown ...
