“…The evolution of notch root radius's influence on K Ic was neglected, which led to a small difference between the predicted and experimental data above room temperature when ρ equals 500 μm. (Sglavo et al, 1999;Deng et al, 2016;Qu et al, 2018).…”

In this work, a physics-based analytical model without any fitting parameters for fracture toughness depending on temperature was proposed. The quantitative relationship between fracture toughness, melting point, Young’s modulus, Poisson’s ratio, and temperature was established. Furthermore, the effect of notch root radius on fracture toughness was investigated, and then we developed a simple theoretical model to characterize the combined effect of temperature and notch root radius on the fracture toughness. Satisfactory agreement between the available experimental measurements and our model predictions was achieved. This study not only advances our in-depth understanding of the quantitative relationship between the temperature and fracture toughness but also provides a powerful and convenient tool to predict the temperature-dependent fracture toughness at different notch root radius.

Fracture of aluminium reinforced with densely packed ceramic particles: link between the local and the total work of fracture

Model composites of pure Al reinforced with 50% ceramic particles are produced by infiltration. The composite fracture energy is measured by J -integral testing. Marked R-curve behaviour is found. The J-R curves exhibit a break in their slope at a well-defined point. This point is shown to denote the onset of macroscopic crack propagation and is used to assess the composite toughness.Toughness reaches values as high as 40 MPa ffiffiffiffi m p . Quantitative metallography and stereoscopic reconstructions of fracture surfaces are used to estimate the local work of fracture in the process zone. The measured (total) fracture energy is about ten times the estimated local fracture energy, for all composites. The main contribution to their total fracture energy is thus from plastic dissipation around the crack-tip; however, the toughness is still dictated by the local fracture energy. This study hence experimentally substantiates the ''valve'' concept in fracture mechanics.
