Paper and paperboard are widely used in packaging products. The material behavior of
paper and paperboard is very complex because different scales need to be considered in …

A phase-field implicit material point method with the convected particle domain interpolation
(PF-ICPDI) is proposed to model the brittle–ductile failure transition in pressure-sensitive …

We present a double-yield-surface plasticity theory for transversely isotropic rocks that
distinguishes between plastic deformation through the solid matrix and localized plasticity …

With elevated confining pressure and low temperatures, geomaterials may exhibit brittle-to-
ductile failure transition due to increased cataclastic flow. In this work, we propose a …

To study the mechanical properties of frozen saline soil under cyclic loading, the cyclic tri-
axial compressive experiments of 36 samples are performed for frozen saline silty clay with …

We introduce a regularized anisotropic modified Cam-clay (MCC) model which captures the
size-dependent anisotropic elastoplastic responses for clay, mudstone, shales, and …

A hyperelastic-plastic coupled constitutive model unified for bonded and unbonded soils is
developed in this paper based on thermodynamics. An elastic potential function applicable …

In order to grasp the rock breaking mechanical characteristics of arc-shaped PDC bit, and
guide the optimization design of bit structure, theoretical calculation models of cutting …

This study is aimed at develo** an anisotropic elastoplastic constitutive model for
geomaterials at finite strain and its stress calculation algorithm based on the fully implicit …

A thermodynamic constitutive model for structured and destructured clays is proposed in this
paper based on thermodynamic principles on the energy storages and dissipations. The …
