Abstract
Some plastics which show outstanding ductility under slowly-applied loads can fail in a brittle manner under impact. This tendency is enhanced by low temperatures and by the presence of a sharp notch, and it is of particular concern for the tough crystalline thermoplastics which have earned most respect as engineering materials. For this and other reasons (including their speed and ease of use), impact tests are accorded a status comparable to tensile tests in specification data for plastics.
