On exactness of the kinematical approach in the structural shakedown and limit analysis

  • J. A. König
Article

Summary

Applying the concepts of limit analysis and shakedown, appropriately defined parameters called generalized stresses and strains are used instead of the actual stresses and strains. It is investigated if the resulting approximations introduce too large errors and if the errors follow only from the simplifying kinematical hypotheses adopted when defining the generalized variables.

Zur Genauigkeit der kinematischen Methode bei Shakedown und Traglast-Verfahren

Übersicht

Bei der Anwendung von Shakedown- oder Traglast-Verfahren werden durch passend gewählte Parameter verallgemeinerte Spannungen und Verzerrungen definiert. Es wird untersucht, ob durch diese Approximation unzulässig große Fehler eingeführt werden.
