Failure analysis of fractured components provides some information about the causes and conditions of fracture. Fractography is an indispensable part of the failure analysis as it is usually the only means by which the failure mechanism can be established. By using fractography, some information such as component’s life, values of the stress intensity factor and the applied stress can be calcul...
