Although there are numerous well-known models of cyclic plasticity defined, in this paper, it is shown that for uniaxial stress state, hysteresis can be defined, based on the experimental data, in one particular rigorously mathematical form and implemented in finite element equations for trusses subjected to cyclic loading in the plastic domain. Using finite element method, equilibrium equations are obtained and algorithm for numerical solution is defined. Some advantages of this approach are underlined, compared with already existing procedures, such as the Bouc-Wen model implemented in SAP2000 program and generalized plasticity model shown on various numerical examples. en dc.publisher Springer Verlag dc.rights restrictedAccess dc.source Archive of Applied Mechanics dc.subject Cyclic plasticity en dc.subject Preisach model en dc.subject Trusses en dc.title Cyclic plasticity of trusses en dc.type article dc.rights.license ARR dc.citation.epage 1526 dc.citation.issue 9-10 dc.citation.other 85(9-10): 1513-1526 dc.citation.rank M22 dc.citation.spage 1513 dc.citation.volume 85 dc.identifier.doi 10.1007/s00419-014-0954-7 dc.identifier.scopus 2-s2.0-84941315085 dc.identifier.wos 000360862200023 dc.type.version publishedVersion
