Determination of crash-relevant parameters by dynamic tensile tests

摘要

The mechanical properties of eight different steels, representing the wide range of steels for automotive application, are determined by accomplishing high speed tensile tests using flat sheet specimens. The steels chosen for investigation are a deep drawing quality DC04, a high strength steel ZSIE340, three dual phase steels with strengths of 600, 800 and 1000 MPa, a TRIP-steel and the two austenitic stainless steels 1.4301 and 1.4318. Tests are carried out at 5 different strain-rates within the range of 5x10~(-3) s~(-1) and 200 s~(-1), all at room temperature.
