An exact consistent tangent stiffness matrix for a second-gradient model for porous plastic solids: Derivation and assessment [PDF]
Mathematics and mechanics of solids, 2022 It is well known that the use of a consistent tangent stiffness matrix is critical to obtain quadratic convergence of the global Newton iterations in the finite-element simulations of problems involving elasto-plastic deformation of metals, especially ...

Strain localization analysis using a multiscale model [PDF]
, 2007 In order to analyze the formability of steels in sheet metal forming, a ductility loss criterion is coupled with a multiscale model. The behavior at the mesoscopic (grain) scale is modeled by a large strain micromechanical constitutive law, which is then

On large deformations of thin elasto-plastic shells: Implementation of a finite rotation model for quadrilateral shell element [PDF]
, 1997 A large-deformation model for thin shells composed of elasto-plastic material is presented in this work, Formulation of the shell model, equivalent to the two-dimensional Cosserat continuum, is developed from the three-dimensional continuum by employing ...

Stabilized four-node tetrahedron with nonlocal pressure for modeling hyperelastic materials [PDF]
, 2008 Non-linear hyperelastic response of reinforced elastomers is modeled using a novel three-dimensional mixed finite element method with a nonlocal pressure field. The element is unconditionally convergent and free of spurious pressure modes.
