A fully implicit, lower bound, multi-axial solution strategy for direct ratchet boundary evaluation : theoretical development

, 2013
Ensuring sufficient safety against ratchet is a fundamental requirement in pressure vessel design. Determining the ratchet boundary can prove difficult and computationally expensive when using a full elastic-plastic finite element analysis and a number ...

Badanie Wpływu Efektu Bauschingera na Plastyczne Przystosowanie się do Konstrukcji (Na Przykładzie Układu Prętowego)

Engineering Transactions, 1974
The strain bardening hypothesis assumed exerts a certain influence on the shakedown of the structure. In the present paper the problem is reduced to an analysis of the influence of the Bauschinger effect on the shakedown process.

Shakedown and ratchetting under tension-torsion loadings : analysis and experiments [PDF]

, 2003
Structural design analyses are conducted with the aim of verifying the exclusion of ratchetting. To this end it is important to make a clear distinction between the shakedown range and the ratchetting range.

Evaluating shakedown under proportional loading by non-linear static analysis

, 2003
A lower bound method for calculating shakedown loads under proportional loading by static non-linear finite element analysis is presented. Stress fields obtained by static analysis and stress superposition are substituted into Melan's lower bound ...

Linear matching method for design limits in plasticity

, 2010
In this paper a state-of-the-art numerical method is discussed for the evaluation of the shakedown and ratchet limits for an elastic-perfectly plastic body subjected to cyclic thermal and mechanical load history. The limit load or collapse load, i.e. the
