For the 4th edition of Trauma Biomechanics all existing chapters referring to traffic and sports have been revised and updated. New scientific knowledge and changes in legal defaults (such as norms and standards of crash tests) have been integrated. Additionally one chapter has been added where biomechanical aspects of injuries affected by high energies are communicated in a new way. The mechanical basics for ballistics and explosions are described and the respective impacts on human bodies are discussed. The new edition with the additional chapter therefore is addressed to a broader audience than the previous one.
