When presetting a step in stress, ideal-elastic solids show an immediate, step-like deformation. After removing the load, the re-formation takes place immediately and completely (see Figure 6.3). In the creep recovery phase, the complete deformation energy which was previously stored by the deformed material during the creep phase immediately can be used up for the re-formation process.

Here, the following applies for the ratio of the finally occurring deformation values:

γe = γmax and γv = 0,

with γmax = γv + γe (see Figure 6.2).
