A plasticity theory for porous metals is proposed. From the stress-strain curves for sintered copper with various apparent densities, the stress-strain curves for pore-free copper is calculated by utilizing the basic equations. The equations are applied to frictionless closed-die compression and the...
Plasticity theory for working of porous metalsThe consideration of different shapes of the yield surface during the compaction of porous materials indicates that an ellipsoid should be recommended due to its simple mathematical form and close description of the actual behaviour of powdered metal (PM) ...

We present a double-yield-surface plasticity theory for transversely isotropic rocks that distinguishes between plastic deformation through the solid matrix and localized plasticity along the weak bedding planes. A recently developed anisotropic modified Cam-Clay model is adopted to model the plastic respon...
Strain-rate dependent and strain-rate independent constitutive models to predict observed phemonena during quasi-static, dynamic or cyclic thermo-mechanical loading, behaviour of granular or porous solids under high confining pressures and at high temperatures, multiscale modeling of various deformation ...
