An edge-based smoothed finite element method (ES-FEM) using three-node linear
triangular elements was recently proposed to significantly improve the accuracy and …

This paper presents a novel numerical procedure for computing limit and shakedown loads
of structures using a node‐based smoothed FEM in combination with a primal–dual …

An effective numerical approach is proposed for calculating limit and shakedown load
multipliers of structures. The key idea is to integrate isogeometric analysis (IGA) based on …

This work investigates the formulation of lower and upper bound finite elements for the yield
design (or limit analysis) of shell structures. The shell geometry is first discretized into …

Structural reliability analysis is based on the concept of a limit state function separating
failure from safe states of a structure. Upper and lower bound theorems of limit and …

The load bearing capacity of engineering structures subjected to varying thermo-mechanical
loading can be determined most conveniently by shakedown analysis. Admittedly, if limited …

The reliability analysis of plates and shells with respect to plastic collapse or to inadaptation
is formulated on the basis of limit and shakedown theorems. Based on a direct definition of …

The paper proposes an efficient numerical method, namely, the elastic modulus reduction
method (EMRM) to calculate lower-bound limit loads of thin plate and shell structures. To …

The main subjects of this chapter are the variational formulations for the computation of a
safety factor in shakedown analysis, the numerical procedures available to implement this …

The article analyses one of possible optimization methodologies for ideal elastic–plastic
structures at shakedown and its application for shallow spherical shells having prescribed …
