Fracture Behavior of Two Biopolymers Containing Notches: Effects of Notch Tip Plasticity
Applied Sciences, 2020 This paper analyzes the notch effect on the fracture behavior of two biomaterials (a brittle bone cement and a ductile dental material) under mode I loading. U-notched Brazilian disk (UNBD) specimens of both materials were tested under remote compression,

Modelling the role of non metallic inclusions on the anisotropic fatigue behaviour of forged steel [PDF]
, 2011 Forged components are known to show high cyclic and monotonic mechanical properties. This is mainly due to a better compactness and a finer microstructure introduced by the forming process. However, this good mechanical behaviour is sometimes a source of

Journal of Materials Research and Technology, 2019 The cyclic deformation and damage behaviors of Al-Si piston alloys are comprehensively studied. It is found that the fatigue cracks mainly initiate from broken primary Si at low temperature and phase/matrix interface debonding at higher temperature.
