OECD category: Audio engineering, reliability analysis
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
