7. Effects of thermal shock
Under the action of temperature, all materials undergo :
or variations in length if they are "free", in the sense of the resistance of materials (RdM), i.e., without connections and/or embeddings;
or internal constraints if they are subject to "links".
To evaluate variations (linear or constraints), let's take as reference median temperatures :
for indoors: T mi ≥ 20 °C ;
for outdoors: T me ≥ 15 °C.
Let's determine the distribution of the gradient ΔT ≥ T mi – T me ≥ 5 °C,...
