The book contains the first physically based and uniform representation of several different phenomena of the time-dependent mechanical properties of glass and metals (steel and Aluminium). It offers a collection of scientifically based formulas for the analysis of the data of stress relaxation, of the background of internal friction, of creep rupture, and of fatigue which is helpful for a better prediction and interpolation of the materials data in practical application.

This will help to improve the technical security in traffic and other fields of practical application of materials.
