Abstract
The fracture resistance of different advanced high strength steel (AHSS) sheets for automotive applications is investigated through conventional tensile tests, fracture toughness measurements and hole expansion tests. Different fracture-related parameters, such as the true fracture strain (TFS), the true thickness strain (TTS), the fracture toughness at crack initiation (wei), the specific essential work of fracture (we) and the hole expansion ratio (HER) are assessed. The specific essential wor...
