Tensile deformation behavior of TRIP-aided bainitic ferrite steel in the post-necking strain region
Science and Technology of Advanced Materials: Methods, 2021 Transformation induced plasticity (TRIP) steels present a remarkable balance of strength and ductility. However, their post-necking hardening behavior, which is required for press-forming and automobile crash simulation, is unreliable because of their ...

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 ...
