Strain localization in softening plasticity without modifying standard constitutive models: a deformable Cosserat approach
Andrea Panteghini, M. B. Rubin
This paper presents a formulation for strain localization in softening plasticity based on a deformable Cosserat model. The approach enables the direct use of standard elastoplasti…
A closed form exact formulation of the spectral representation of a second-order symmetric tensor and of its derivatives
Andrea Panteghini
The spectral decomposition of a symmetric, second-order tensor is widely adopted in many fields of Computational Mechanics. As an example, in elasto-plasticity under large strain a…
A micropolar isotropic plasticity formulation for non associated flow rule and softening featuring multiple classical yield criteria. Part II -- FE integration and applications
Andrea Panteghini, Rocco Lagioia
A Finite Element procedure based on a full implicit backward Euler predictor/corrector scheme for the Cosserat continuum is here presented. Since this is based on invariants of the…
A micropolar isotropic plasticity formulation for non-associated flow rule and softening featuring multiple classical yield criteria Part I -- Theory
Andrea Panteghini, Rocco Lagioia
The Cosserat continuum is used in this paper to regularize the ill-posed governing equations of the Cauchy/Maxwell continuum. Most available constitutive models adopt yield and pla…
