A General Return-Mapping Framework for Fractional Visco-Elasto-Plasticity [PDF]
Fractal and Fractional, 2022 We develop a fractional return-mapping framework for power-law visco-elasto-plasticity. In our approach, the fractional viscoelasticity is accounted for through canonical combinations of Scott-Blair elements to construct a series of well-known fractional

An improved return-mapping scheme for nonsmooth yield surfaces: PART I - the Haigh-Westergaard coordinates [PDF]
arXiv.org, 2015 The paper is devoted to the numerical solution of elastoplastic constitutive initial value problems. An improved form of the implicit return-mapping scheme for nonsmooth yield surfaces is proposed that systematically builds on a subdifferential ...

Return-mapping algorithms for associative isotropic hardening plasticity using conic optimization
Applied Mathematical Modelling, 2020 We present a mathematical programming approach for elastoplastic constitutive initial value problems. Consideration of the associative plasticity and a linear isotropic hardening model allowed us to formulate the local discrete constitutive equations as ...

RETURN MAPPING FOR CREEP AND PLASTICITY SPLIT [PDF]
Blucher Mechanical Engineering Proceedings, 2014 Within the range of validity of the small strain theory, the strain is additively decomposed in an elastic or reversible strain and an inelastic or irreversible strain.The inelastic strain consists of a plastic component quickly developed under loading, and a viscous or creep component develops that slowly under loading.Most frequently, both components
