Fracture characteristics of PEEK at various stress triaxialities [PDF]
Journal of the Mechanical Behavior of Biomedical Materials, 2016 Polyether-ether-ketone (PEEK) is an alternative to metal alloys in orthopaedic applications. It gives significant advantages including excellent mechanical properties and non-toxicity. In this work, a set of specimens with different notched radii were selected to examine the effect of triaxial state of stress on the fracture behavior of PEEK ...
