Abstract

The notion of a deformable continuous medium comes to mind when we observe the kind of solid deformations shown in Figs. 1 and 2, during cold or hot forming processes, or again the flow of a liquid, or the expansion and compression of a gas. From this kind of experience, the observer extracts the idea that certain problems can be treated on a macroscopic scale by assimilating the material to a ‘continuous’ medium, without in any way contradicting the assumptions of microscopic physics.
