The method is based on the lower bound approach by Melan extended to the hardening using a two-surface model. Both the yield and the bounding surface are deﬁned by the von Mises condition. Melan’s shakedown theorem leads to a nonlinear convex optimization problem. This is solved by the interior-point algorithm ipsa recently developed by the authors. In this paper, theoretical and numerical aspects will be presented as well as numerical examples from mechanical engineering. dc.format.extent 12 p. dc.language.iso eng dc.publisher CIMNE dc.subject Àrees temàtiques de la UPC::Matemàtiques i estadística::Anàlisi numèrica::Mètodes en elements finits dc.subject.lcsh Finite element method dc.subject.lcsh Plasticity -- Mathematical models dc.subject.lcsh Plasticity dc.subject.other Shakedown Analysis, Direct Methods, Interior-Point Algorithm, Limited Kinematical Hardening, Nonlinear Programming dc.title Interior-point algorithm for shakedown analysis accounting for limited kinematical hardening dc.type Conference report dc.subject.lemac Elements finits, Mètode dels dc.subject.lemac Plasticitat -- Models matemàtics dc.subject.lemac Plasticitat dc.rights.access Open Access local.citation.contributor COMPLAS XI local.citation.publicationName COMPLAS XI : proceedings of the XI International Conference on Computational Plasticity : fundamentals and applications local.citation.startingPage 1415 local.citation.endingPage 1426
