- ÍtemAnálisis de falla en herramientas manuales agrietadasCamargo Capador, Johnatan Camilo; Reyes Bejarano, Elkin Rodrigo; Rivera Aranda, Carlos Andrés; Cendales Ladino, Edwin DaríoThe object of the present investigation is to determine the factors that induced mechanical failures to two mechanical components, used as tools of the industry which are a 14 mm socket wrench and a 120 mm bar tool extension. In the first place, an investigation of the theoretical foundations was carried out; corrosion under stress, and fatigue, which helped to understand more thoroughly what could have been the main cause for the pieces to be affected to these determined fractures. Then the description of each of the affected components was carried out, and in addition to their respective faults produced in each of the pieces. Then the respective metallographic observations of the components were carried out, likewise hardness tests were also carried out. Finally, it was established that the socket wrench fractured in a fragile manner due to stress corrosion cracking, the extensor failure by nucleation of fatigue. (Parts of the text)
