GB/T 33061.1-2016 Plastics—Determination of dynamic mechanical properties—Part 1:General principles
Basic Information
Scope
The various parts of GB/T 33061 specify methods for determining the dynamic mechanical properties of rigid plastics within the range of various online viscoelastic behaviors. This part is an introduction, including common definitions and various aspects of the test methods in the subsequent sub-parts.
The results obtained from different deformation modes cannot be directly compared. For example, in tensile vibration, the stress acting on the entire thickness of the sample is consistent, while in bending measurement methods, the surface properties of the sample are the main influencing factors.
Only when the structure of the sample is uniform and the stress-strain relationship is linear, can the data obtained from bending and tensile tests be comparable.
