All natural materials (rubber, protein, cellulose) and plastics contain molecules as their smallest particles, which in turn consist of a large number of atoms. The term ‘macromolecule’ tak...") | ||||

A material value thus represents a numerical value with the associated physical unit of the property (see Material Parameter|material p...") | ||||

The mechanical work required to do this is stored in the form of potential energy (increase in internal energy) an...") | ||||
