Limit and Shakedown Reliability Optimization Accounting for Nonlinear Geometric Effects
In this chapter, the relation between deterministic, stochastic and design parameters is explained. Differences between deterministic and reliability-based optimisation are pointed out. A formulation of the system reliability optimization with the limit a

PREFACE The integrity assessment of structural elements susceptible to operate beyond the elastic limits under variable repeated thermo-mechanical loads is an important task in many situations of structural engineering. Examples of such situations can be found in both mechanical and civil engineering (transportation technologies, pressure vessels, general machinery, constructions such as dams, pavements, offshore platforms, pipelines and buildings in seismic zones). The so-called "direct" or "simplified" methods based on the shakedown theorems and their specialisation to limit theorems are receiving increasing attention for the prediction of structural failure in the inelastic range, although they basically originated decades ago within classical plasticity. Reasons for such revival are, first, that these methods provide the information which are essential in practice (e.g. safety factor and collapse mechanisms) by means ofprocedures potentially more economical than step-by-step inelastic analysis; second, they only need a minimum of information on the evolution of loads as functions of time (many technical problems do not permit to assume the precise knowledge of the loading history for time-marching simulations). These methods are the subject of the present book. It reflects the lectures held in
