Specimens for the bending tests with the chevron notch are standardized for the
evaluation of the fracture toughness of various materials. The main advantage of this test
set-up is that no sharp pre-crack has to be introduced, because a sharp crack is formed
during loading at the beginning of the test. Furthermore, no crack length measurement is
required, and a stable crack growth can be reached due to geometry of the notch. In this
contribution a difference of the ligament area of the specimens with the straight through
notch and the chevron notch was investigated
