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 …

Hard magnetorheological elastomers (h-MREs) are essentially two phase composites
comprising permanently magnetizable metallic inclusions suspended in a soft elastomeric …

The failure behavior of geological materials depends heavily on confining pressure and
strain rate. Under a relatively low confining pressure, these materials tend to fail by brittle …

We investigate three aspects of material behavior in this ninth installment of the Cam-Clay
series, namely, anisotropy, heterogeneity, and viscoplasticity. The main focus of the paper is …

We present a continuum framework for coupled solid deformation–fluid flow in anisotropic
elastoplastic porous media. A thermodynamic formulation of the coupled processes gives …

Accurate prediction of strength in rocks with distinct bedding planes requires knowledge of
the bedding plane orientation relative to the load direction. Thermal softening adds …

Fluid flow in isotropic porous media with one porosity scale is a well understood process
and a common scenario in numerous simulations published in the literature. However, there …

The critical state is significant to the mechanical behaviors of granular materials and the
foundation of the constitutive relations. Using the discrete element method (DEM), the …

We present a continuum framework to simulate fluid flow through anisotropic elastoplastic
media with double porosity. Two effective stress measures σ′ and σ′′ emerge from the …

This book describes thermoelastic and inelastic deformation processes in crystalline solids
undergoing loading by shock compression. Constitutive models with a basis in geometrically …
