porous solidscracksvoidsmodelsdeformation theory/ A4630J Viscoelasticity, plasticity, viscoplasticity, creep, and stress relaxationA plasticity theory is developed for a solid weakened by numerous cracks or voids. The treatment is completely isotropic and would be suitable whenever the voids are nearly ...
The thermomechanics of porous solids including the implications of the second law of thermodynamics are studied through application of a mixture theory. This derivation suggests that the pore collapse relation should express the rate of change of either the volume fraction or the distention ratio as ...

Plaster of Paris is a brittle, porous solid, easy to shape, which has potential as a model material for the study of brittle, porous, solids such as ceramics, rocks and cement. This paper describes the mechanical properties of plaster of Paris — modulus, strength, fracture toughness, etc....
The traditional unified viscoplasticity constitutive model can be only applied to metal materials.The study of the unified constitutive theory for metal materials has discovered the correlation between the classical plasticity theory and the unified viscoplasticity constitutive model,thus leading to the con-...
The accuracy of the proposed numerical method is addressed through a comparison of the numerical results and the analytical solutions for the transient response of saturated porous solids. An elasto-plastic constitutive model based on the non-linear kinematic hardening rule is formulated to describe ...
Metamaterials composed of different geometrical primitives have different properties. Corresponding to the fundamental geometrical forms of line, plane, and surface, beam-, plate-, and shell-based lattice metamaterials enjoy many advantages in many aspec
For instance, the various porous materials such as active carbon, zeolite, honeycomb ceramics, etc. were developed as supports to improve the mechanical strength and the stability of transition metal oxides [46]. These catalysts were reported to enhance the removal efficiencies of pollutants by O3....
