An Early Upper Bound Method for Shakedown of Beams and Frames,ctory chapter in the Proceedings volume, serves at least to make evident the enormous increase in both the scope and the general sophistication of the more recent research efforts in this area of structural mechanics.

Shakedown at Finite Elasto-Plastic Strains,y applying the well-known statical shakedown theorem of Melan , which leads to a lower bound of the load factor. Dual to the Melan’s theorem Koiter formulated a kinematical shakedown theorem yielding an upper bound of the load factor. While many publications deal with shakedown of structures

Shape Optimization under Shakedown Constraints,ry variations within direct analysis, shakedown analysis and variational design sensitivity analysis based on convected coordinates. Using a special formulation of the optimization problem of shakedown analysis, we easily derive the necessary variations of residuals, objectives and constraints. Subs

Numerical Simulations of Thermo-Viscoplastic Flow Processes under Cyclic Dynamic Loadings,lic loadings..A general constitutive model of elasto-viscoplastic damaged polycrystalline solids is developed within the thermodynamic framework of the rate type covariance structure with a finite set of the internal state variables. A set of the internal state variables is assumed and interpreted s

Shakedown of Elastic-Plastic Structures with Non Linear Kinematical Hardening by the Bipotential Apccount is shown to be a non-associated one. For this purpose, the implicit non-standard material model is introduced through the bipotential approach. After some remarks on the theoretical aspects, an analytical example of a thin walled tube under constant traction and alternating torsion is given a
