On the Wellposedness of the Chaboche Model [PDF]
, 1998 We formally state and prove the wellposedness and the local Lipschitz continuity of the multisurface stress-strain law of nonlinear kinematic hardening type due to Chaboche within the space of time-dependent tensor-valued absolutely continuous functions. The results also include the more general case of a continuous family of auxiliary surfaces.

High Temperature Mechanical Constitutive Modeling of a High-Nb TiAl Alloy
Journal of Aeronautical Materials, 2018 Uniaxial tensile, low cycle fatigue, fatigue-creep interaction and creep experiments of a novel high-Nb TiAl alloy (i.e. Ti-45Al-8Nb-0.2W-0.2B-0.02Y (atom fraction/%)) were conducted at 750℃ to obtain its tested data and curves.

Comparative study of fatigue assessment of defective material based on affected depth
Comptes Rendus. Mécanique, 2022 In this work, we propose a comparative study of fatigue assessment of artificial surface defects based on affected depth (AD). The defect is assumed to be a void (semi-spherical, elliptical, or circumferential notches) on the surface of a material ...

Chaboche's Viscoplasticity Model for Strain – Space Plasticity
Procedia Engineering, 2017 Abstract To obtain reliable stress and strain fields using finite-element simulations, the applied constitutive equations, in general formulated in terms of evolution equations for the stresses and a set of state variables, that should be able to describe hardening properties as well as micro structural aspects with sufficient accuracy.
