Advanced evaluation of the instrumented Charpy V-notch test One important material property in mechanical engineering is the fracture toughness, which describes the resistivity of the material against crack propagation. However, this material property is very expensive to evaluate. Therefore, a simplified technological test setup was introduced decades ago, to estimate the fracture behavior using the impact energy. The most frequently used, very simple measurement system is the Charpy V-notch test. The basic setup only returns the so-called impact energy. By using several strain gauges and an inductive eddy current sensor, more detailed information during the test can be recorded. The main result is the force-displacement diagram, which can be evaluated and used for further interpretation of the material behavior. |
