Erratum to: The shielding effect of the crack-tip plastic zone [PDF]
International Journal of Fracture, 2011 which should be regarded by the reader as the final version. Fortunately, this mistake has negligible effect on the numerical results shown in Figs. 2, 3 and 4, so that Eqs. (19) and (20) are applicable. In addition, the non-zero components of the Eshelby tensor given in Eq.

Superhard bulk high-entropy carbides with enhanced toughness via metastable in-situ particles
Nature Communications, 2023 Despite the extremely high hardness of recently proposed high-entropy carbides (HECs), the low fracture toughness limits their applications in harsh mechanical environment. Here, we introduce a metastability engineering strategy to achieve superhard HECs

Effect of stiff substrates on enhancing the fracture resistance of Barium Titanate thin films
Materials & Design, 2023 Damage tolerance of a thin film attached to a substrate is dependent on several parameters such as film thickness, film orientation, residual stresses, nature of interfaces, microstructure and defects present.

CRACK-TIP SHIELDING AND ANTI-SHIELDING BY A BIMATERIAL INTERFACE [PDF]
, 2020 Spacial variations of the mechanical properties have a shielding or anti-shielding effect on the crack tip by inducing an additional crack driving force term, the material inhomogeneity term, C inh .

Characterisation of crack tip fields—CCTF5 [PDF]
, 2020 Single parameter characterisation of the crack/notch tip field using fracture mechanics parameters like K, J, or CTOD has been extremely powerful in advancing predictive technologies for critical or subcritical crack growth. It has also become clear over

A Dislocation Perspective on Strength and Toughness in Ceramics
Advanced Engineering Materials, EarlyView.Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Advanced Engineering Materials, EarlyView.Functionally graded metal–ceramic femoral stems are engineered through continuous UMAT‐based stiffness tailoring, eliminating discrete material interfaces while enhancing biomechanical compatibility. Low‐index power‐law gradation optimizes load transfer, reduces stress shielding, and controls implant–bone micromotion, highlighting a materials‐design ...

Crack tip microplasticity mediated by microstructure gradients [PDF]
, 2021 Traditional fracture theories infer damage at cracks (local field) by surveying loading conditions away from cracks (far field). This approach has been successful in predicting ductile fracture, but it normally assumes isotropic and homogeneous materials.
