OSSA, Edgar Alexander  and  PANIAGUA, Marco Aurelio. Failure analysis of a hydraulic press clamp. Rev.fac.ing.univ. Antioquia [online]. 2008, n.44, pp.30-35. ISSN 0120-6230.

This paper describes the analysis and investigation of the causes of the failure of an hydraulic press jaw face grip. Analysis of the fractured surfaces indicated the creation of cracks due to stress concentrators as a result of defective design. On the other hand, metallographic examination revealed the presence of aligned clusters of primary carbides that along with the stress concentrators induced the premature failure of the grip.

Keywords : Clamping; grip; design failure; metallography; fractography.
