20.500.12556/RUL-152014 A coupled simulation of parametric porous microstructure and stress-strain behavior in mechanical components under variable cyclic loads A coupled algorithm is proposed which first considers the creation of porous structure of the material and then the simulations of response of mechanical components with porous structure to a variable load history. The simulations are carried out by the Prandtl operator approach in the finite element method (FEM) which enables structural simulations of mechanical components subjected to variable thermomechanical loads. Temperaturedependent material properties and multilinear kinematic hardening of the material can be taken into account by this approach. Several simulations are then performed for a tensile-compressive specimen made of a generic porous structure and mechanical properties of Aluminium alloy AlSi9Cu3. Variable mechanical load history has been applied to the specimens under constant temperature conditions. Comparison of the simulation results shows a considerable elastoplastic stress-strain response in the vicinity of pores whilst the surface of the gauge-length of the specimen remains in the elastic region of the material. Moreover, the distribution of the pore sizes seems more influential to the stress-strain field during the loading than their radial position in the gauge-length. cyclic loading elastoplasticity finite element analysis porous structure ciklična obremenitev elastoplastičnost analiza končnih elementov porozna struktura true false true Angleški jezik Slovenski jezik Članek v reviji 2023-10-27 11:48:57 2023-10-27 11:49:01 2023-10-28 03:41:36 0000-00-00 00:00:00 2023 0 0 10 str. no. 5 Vol. 12 Oct. 2023 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-10-17 2025-10-17 539.3 Y509-2337 10.12989/csm.2023.12.5.409 170212355 Seruga_..._A_coupled_simulation_of_parametric_porous_microstructure_....pdf Seruga_..._A_coupled_simulation_of_parametric_porous_microstructure_....pdf 1 E4435DBD641EDAE696329F17483FE84A 92bba0c594df54f997a873291295dac07f5cbeeee5f165b7de9d91ee21c0d711 1fccb217-74b0-11ee-ad91-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177190 http://www.techno-press.org/content/?page=article&journal=csm&volume=12&num=5&ordernum=2 1 123b142a-74ae-11ee-ad91-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=177189 Fakulteta za strojništvo 0 0 0
