o:30591 Thermomechanics of Soft Inelastics Bodies with Application to Asphalt Behavior en Abstract: Thermomechanical behavior of hot mix asphalt (HMA) is considered. Its highly irregular microstructure is covered by the hierarchical approach. A brief survey of endochronic thermodynamics precedes constitutive consideration. Two constitutive models are discussed: classical Perzyna’s approach and tensor representation based approach. The second is superior due to its possibility to cover properly diverse multiaxial nonproportioal stress-strain histories. However, due to availability of experimental data the first model is applied to rutting problem through Abaqus FEM code with material user subroutine developed by the authors. Vakulenko’s thermodynamic time appropriate for aging is incorporated. Hyperelasticviscoplastic behavior is considered and some preliminary results are presented. Keywords: endochronic memory, nonlinear hyperelastoplasticity, thermodynamic restrictions, asphalt rutting 1552099 10.2298/TSCI130812184K 1552101 0354-9836 2023-08-16T12:24:09.666Z 44 no 46 Ljudmila T.
