Titel
Investigations on damage evolution and cleavage based on combined experimental and numerical methods
Abstract
The brittle failure of ferritic steels was examined in experimental and numerical investigations using a wide range of specimens. Finite element analyses were performed to analyze the mechanisms and conditions of fracture initiation. The investigations show a good agreement between the initiation sites and the location of maximum stresses. The effect of the local constraint on the fracture toughness was described by a shift of the reference temperature depending on the secondary fracture parameter.
