A hypoplastic constitutive model is implemented in a smoothed particle hydrodynamics code
for the first time. An improved wall boundary treatment is presented for better performance …

In this paper, a practical meshfree large deformation method (MFLDM) is proposed for
numerical analysis in geotechnical engineerings, including: soil foundation, slop, dam, etc …

We investigate geometrically exact generalized continua of Cosserat micropolar type. A
variational form of these models is recalled and extended to finite-strain elasto-plasticity …

In this paper, an automated adaptive remeshing procedure is presented for simulation of
arbitrary shape crack growth in a 2D finite element mesh. The Zienkiewicz–Zhu error …

We investigate the numerical response of the linear Cosserat model with conformal
curvature. In our simulations we compare the standard Cosserat model with a novel …

Efficient computational modelling of problems including both material and geometric
nonlinearities remains challenging. Often these problems are modelled with adaptive finite …

In this paper, a micro-polar continuum model is presented based on the Cosserat theory for
3D modeling of localization phenomena. Since the classical continuum model suffers from …

The standard finite element models, ie the finite element methods that use the classical
continuum models, suffer from the excessive mesh dependence when a strain-softening …

This work is the second of a two-part investigation into the use of discontinuous Galerkin
methods for obtaining approximate solutions to problems of classical and gradient plasticity …

In this paper, the three-dimensional automatic adaptive mesh refinement is presented in
modeling the crack propagation based on the modified superconvergent patch recovery …
