Although it can be easily applied to many conventional models, its main advantages arise when applied to models with multiple strongly coupled dissipation mechanisms, where the direct construction of the coupled yield conditions and flow rules may be challenging. However, this usually requires a more complex numerical treatment of the resulting sequence of time-incremental boundary value problems resolved via the finite element method. This contribution presents, compares and discusses two genuine minimization approaches - the staggered solution procedure relying on alternating minimization and the monolithic approach employing global minimization - for an advanced constitutive model of shape memory alloys. cav_un_auth*0457147 Computational mechanics 2023 /38./ 20231023 20231025 Srní CZ JG 20000 20300 20302 2024 4 UTIA-B 10000 10100 10101 4 A 4a 20231213114025.3 PR UTIA-B BA RVO:61388998 RVO:67985556 https://hdl.handle.net/11104/0349462 cav_un_auth*0296535 Ústav teorie informace a automatizace AV ČR ÚTIA AV ČR CZ S 2023 Soubory v repozitáři: 0579417_Numerical implementation of incremental minimization_CM23_Frost.pdf SCOPUS PUBMED WOS pdf cav_un_epca*0577231 Computational mechanics 2023.
