A new computational approach combining the Smooth Particle Hydrodynamics and a
constitutive model that possesses an intrinsic length scale is proposed in this study for …

Understanding the mechanism of disasters and designing protection systems for cold region
tunnels require a fundamental analysis of the constitutive model of rock under freeze–thaw …

Energy conversion is an essential driving force of shale anisotropic deformation, damage
initiation and evolution. In this study, theoretical calculations of five energy indexes (total …

Localised failure of geomaterials in the form of cracks or shear bands always requires
special attention in constitutive modelling of solids and structures. This is because the …

Localised failure in geomaterials invalidates the assumption of homogeneous deformation
that constitutive models based on continuum mechanics rest on. In such cases, the …

The crack closure effect of rock materials plays a key role in the evaluation of its
compressive mechanical behavior. Based on the effective medium theory, an exponential …

Confining pressure, strain rate and anisotropy are three essential factors that affect the
mechanical behaviors of shale. In this study, a damage constitutive model including the …

A rational study has been made to describe the behavior of anisotropic granular materials by
a hypoplastic constitutive equation. The concept of the microstructure tensor in describing …

The focus of this paper is the transition from diffuse to localized failure of sandstone and
concrete specimens under uniaxial compression and correlation between macro responses …

The key failure mechanism of rock mass subjected to compressive loads is due to the
damage localization. Conventional methods can not be applied to study the dynamic …
