Notch strength

The notch resistance , even tear resistance and tear resistance , is the property of a substance not to tear further even in the presence of a notch.

materials

This mechanical quantity is an important material property . Like all plastics, polyvinyl chloride (PVC) , for example, has only low notch strength .

DIN standards for notch strength
