3.6.3. Mechanical Properties

For the calibration of the material model described above, or for mechanical dimensioning, material parameters of the selected polymer have to be found. Because of viscoelastic behavior, it is often only possible to obtain relative parameters. The values have a comparative character and should not be used for the structural dimensioning of components. To get absolute values, some testing methods have to be modified, like a strain-controlled tensile test. For replication processes, the analysis of behavior during demolding is essential. Typical deformations during demolding are characterized by deformation based on tensile load. Therefore, tensile experiments allow one to characterize the behavior of the polymer ...
