Concrete double-K fracture toughness and fracture energy influenced by porosity and pore size [PDF]
Scientific ReportsThe diameter and quantity of internal pores in concrete significantly influence its mechanical properties. While existing studies predominantly focus on the influence of pore quantity, this study utilizes pre-fabricated pores made from polystyrene ...

Fracture Diodes: Directional Asymmetry of Fracture Toughness [PDF]
Physical Review Letters, 2021 Toughness describes the ability of a material to resist fracture or crack propagation. It is demonstrated here that fracture toughness of a material can be asymmetric, i.e., the resistance of a medium to a crack propagating from right to left can be significantly different from that to a crack propagating from left to right.

Modeling the effect of temperature and notch root radius on fracture toughness
Frontiers in Materials, 2022 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 ...

Fracture toughness of graphene [PDF]
Nature Communications, 2014 Perfect graphene is believed to be the strongest material. However, the useful strength of large-area graphene with engineering relevance is usually determined by its fracture toughness, rather than the intrinsic strength that governs a uniform breaking of atomic bonds in perfect graphene.
