摘要：

The split Hopkinson's pressure bar test is a part of a group of testing methods used to determine dynamic behavior of various materials in an interval of strain rate from 100 s(-1) to 10(3) s(-1). The article describes the practical application of the testing method for aluminum alloy EN AW 6082. This alloy is used for colde-xtruded parts (components of car airbags). Since the strain rate of cold forming technologies reaches up to 1000 s(-1), it is necessary to determine the material ' s behavior at these strain rate values.
