calculation friction / stress

it is not a legal term, but an engineering one.
in physics, this law measures the relation between applied stress/tension and the resulting deformation.

If the law is a legal one.

If the law is more like a sort of principle, then perhaps it is more like "making a thing what it is".

similar to Hooke's law

Hooke's Law and Dielectrics


What is a constitutive equation? For mechanical problems, a constitutive equation describes how a material strains when it is stressed, or vice-versa. Constitutive equations exist also for electrical problems; they describe how charge moves in a (dielectric) material when it is subjected to a voltage, or vice-versa.
Engineers are already familiar with the most common mechanical constitutive equation that applies for everyday metals and plastics. This equation is known as Hooke's Law and is written as:




In words, this equation states: Strain = Compliance × Stress.
However, since piezoelectric materials are concerned with electrical properties too, we must also consider the constitutive equation for common dielectrics:

... 3. The equilibrium condition for the stress is to be supplemented by the constitutive (Hooke's) law. ... the constitutive law (9) with the defining equation. ffl. 11. =. ...
