__FORCETOC__

When used as construction materials for plastic components, [[Plastics | plastics]] are generally regarded as [[Material & Werkstoff | materials]] with particularly high [[Ductility Plastics | ductility]]. However, it can be deduced from the large number of cases of damage that a number of influencing factors, such as

* design-related [[Notch | notches]],
* production-related defects,
* high stress [[Velocity | velocity]],
* multi-axial [[Stress | stress]] states,
* surrounding media, and
* low temperatures

greatly increase the susceptibility of such materials to brittle fracture [1].

When analysing the mechanical properties and evaluating the deformation and [[Fracture Behaviour | fracture behaviour]], the combination of the microscopic and macroscopic approach van achieve decisive progress with regard to the clarification of damage mechanisms.

'''Figure 1''' shows the factors influencing the [[Fracture Behaviour | fracture behaviour]] on the part of the [[Stress | stress]], the geometry, the material and the environment (blue marked fields).

The factors influencing the fracture behaviour are the stress state and the loading speed on the stress side, the dimensions and the component shape as well as discontinuities and cracks on the geometry side, the [[Polymers & Structure | microstructure]] (morphology) and the chemical composition on the material side and finally the temperature and the surrounding media.
