Computational Mechanics at the Mesoscale by A. Needleman, Acta Mater. 48, 105 (2000) offers a deeper perspective on the multiscale aspects of modeling plasticity than that offered in the current chapter. Needleman s discussion descends from the perspective of crystal plasticity to the level of dislocation dynamics. 

Johnson (1970) analyzed subaerial debris flows by means of a steady-state Bingham model (plastic-viscous model with soil yield resistance, k, and linear viscosity, r ). In Johnson s model the shear stress (t ) resisting displacement is related to the velocity of movement (ra ) in the following expression ...

An example of crashworthiness design of a vehicle structure where a plastic hinge concept has been used to model plastic deformations of the vehicle structure during the impact, is solved to demonstrate the use of the methodology. 

Creep testing also demonstrates another term commonly used in material testing, that is, deformation. There are two types of deformation that may arise after a stress is applied to a material elastic deformation and plastic deformation. Elastic deformation refers to materials whose shape changes temporarily, and once the force is removed, the material resumes its original shape this is equivalent to the spring representation in viscoelasticity models. Plastic deformation refers to nonreversible changes in shape, represented by the dashpot here. It is interesting to note that even for metals, the term plastic deformation is used to indicate that a material has been deformed in a way that cannot be recovered.
