With the instrumented Class H-4 configuration, the striker contains a built-in force transducer that records the full force–time history during impact. This allows the system to measure much more than just absorbed energy. The software can capture the maximum force reached during the strike, the energy absorbed before that maximum (pre-maximum energy Wm) and the energy absorbed after the maximum as the crack continues to grow.

It can also determine characteristic forces linked to different parts of the fracture process, such as general yield force, brittle fracture initiation force and arrest force. These values help engineers see whether a material behaves more ductile or brittle and how the crack propagates under dynamic loading.

By combining these parameters with the traditional energy value, the instrumented setup gives a detailed picture of fracture behavior that is useful for R&D, material comparison, and critical applications where simple energy numbers are not enough.
