Chapter
The mechanical testing of a material is a simple procedure that records the response of a specimen to an external effect. The recorded result reflects some kind of damage process that takes place in the material for given external conditions. This damage process can be considered to be the response of a self-organised system. If a single damage process takes place during the testing (or one process predominates), then the simplest testing evaluation procedure would be based on a power law relationship with two parameters, i.e. the response of the material is proportional to the external effect. This approach raises two questions. Why does a single (unknown) damage process require two parameters to characterise it? If the same external conditions are applied for a group of materials and the responses of those materials (the damage process) are also the same, is there a correlation of the power relationship parameters between the materials in the group? These questions will be discussed in this paper.
