Microscopic processes of creep,ope, with simple crystallographic nets: close-packed hexagonal as Mg, Zn, Ti; face-centered cubic (which is another close-packed structure for a set of spherical atoms), as Al, Cu, Ni; or body-centered cubic as Fe (below 911ºC), Cr, W. The macroscopic behavior of metals will allow us to define some basic concepts.

Variational theorems and the finite element method, (which may be vectorial) has to obey. In many cases, these equations are equivalent to the condition that the variation of some functional .(.), when . is modified by an infinitesimal quantity from its correct value, is zero to the second order. (This condition is written as δ. = 0.)

The rigid-plastic model,sible strain, the plastic strain, which adds to the elastic strain; (2) when the load increases further monotonically, the plastic strain increases monotonically too; but, when the load is kept constant, the strain remains constant, there is no creep.

Viscoelasticity and transient creep,troduced. The principle of local action (Section 5.1) will always be assumed. Therefore, the constitutive relationship involves the values at some material point of the diverse variables and of their space derivatives of low order only. Nevertheless, it may include not only the actual values, but the past ones, ..
