20.500.12556/RUL-169615 Cyclic thermomechanical elasto-viscoplasticity implementation using user material interface The paper introduces a user material for Abaqus, detailing the modeling of elasto-viscoplasticity under diverse thermomechanical conditions. Converting constitutive equations into a robust code requires extensive efforts to solve numerous crucial numerical challenges. In addition to deriving the equations, detailing the code is also crucial for an efficient implementation of a rheological model. The algorithm for multiaxial Prandtl operator approach presented here provides both. The subroutines of the numerical code are explained in detail and solutions to ensure numerical stability are demonstrated. The multiaxial Prandtl operator approach allows a simple and effective calculation of fatigue damage, creep damage, e.g., or dissipated energy using available uniaxial methods. To demonstrate practical application, the paper illustrates the usefulness of the code by analyzing perforated plates under tension–compression and shear loading. This contribution enriches the computational modeling of elasto-viscoplasticity for the finite element method. finite element method thermomechanical loading elasto-viscoplasticity fatigue creep dissipated energy true false true Angleški jezik Ni določen Članek v reviji 2025-06-06 09:04:12 2025-06-06 09:04:20 2025-06-08 04:25:32 0000-00-00 00:00:00 2025 0 0 26 str. iss. 11, art. 2512 Vol. 18 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.3:536 1996-1944 10.3390/ma18112512 238506499 Nagode_..._Cyclic_Thermomechanical_Elasto-Viscoplasticity.pdf Nagode_..._Cyclic_Thermomechanical_Elasto-Viscoplasticity.pdf 1 226BF49E5F7240D6B94CB1651A13956E cec99134ab7b23c2056bb3f43104bd497ba1a6a284f538ccc0f8c5276801be16 693533dc-42a3-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=211120 https://www.mdpi.com/1996-1944/18/11/2512 1 27748803-42a3-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=211119 Fakulteta za strojništvo 0 0 0
