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...") | ||||

Depending on the type of installation, a distinction is made between standing and horizontal testing machines. Standing testing machines are available in table-top and standard designs (see illustration). Depe...") | ||||

However, as '''Fig. 1''' shows, there is still proportionality between stress and strain. In this case, unlike most metallic materials, the requirement of linear proportion...") | ||||

The stationary support is called the crosshead, and the support that moves up or down is th...") | ||||
