During the evaluation of mechanical testing results power type relatio
nships having two parameters, are widely used. The most frequently use
d laws are the following: Paris law in evaluation of fatigue crack pro
pagation data, Manson-Coffin equation in LCF testing results, relation
ship between the creep rate and stress at constant temperature, life t
ime and stress in the case of creep or fatigue, etc. In these relation
ships the material responses are characterised by two experimentally d
etermined parameters. In this paper it will be pointed out that the pa
rameters in each of these equations are not independents. They have a
physically backgrounded correlation.
