| Abstract: | The plane strain fracture toughness KIC of ultra high strength D406A steel forgings for solid motor cases is tested to obtain a practical KIC in the important portion of the case and to find a range of carbon content for compatibility of material strength with fracture toughness. The results provide a test basis for the case design, its safe use and the fracture analysis. |
