STUDY ON THE DETERMINATION METHOD OF CONSTRAINT DEPENDENT FRACTURE TOUGHNESS OF STRUCTURE
Jixie qiangdu, 2017 The fracture toughness of material are affected by the constraint at crack tip. In order to assess the structural integrity of cracked structure accurately,it needs to obtain the constraint dependent fracture toughness. In this paper,based on the unified

Low‐Velocity Penetration Impact Behavior of Triply Periodic Minimal Surface Strut‐Based Lattices
Advanced Engineering Materials, EarlyView.Triply periodic minimal surface (TPMS)‐based lattices are gaining attention for their multifunctional properties in applications as aeronautics and automotive, which involve low‐velocity impact loading. This work evaluates the low‐velocity penetration impact behavior of five distinct TPMS architectures.

Predicting Fracture Energies and Crack-Tip Fields of Soft Tough Materials [PDF]
arXiv, 2015 Soft materials including elastomers and gels are pervasive in biological systems and technological applications. Whereas it is known that intrinsic fracture energies of soft materials are relatively low, how the intrinsic fracture energy cooperates with mechanical dissipation in process zone to give high fracture toughness of soft materials is not well

Axisymmetric displacement flows in fluid-driven fractures [PDF]
Journal of Fluid Mechanics. 2022;953:A36Displacement flows are common in hydraulic fracturing, as fracking fluids of different composition are injected sequentially in the fracture. The injection of an immiscible fluid at the center of a liquid-filled fracture results in the growth of the fracture and the outward displacement of the interface between the two liquids. We study the dynamics of

From Nature to Engineering: Mortar Volume and Interfacial Mechanics in Bioinspired Ceramics
Advanced Engineering Materials, EarlyView.Inspired by natural armors like nacre, this study explores how varying the volume fraction of the soft mortar layer impacts the interfacial strength and toughness of bioinspired ceramics. Experimental and computational analysis reveals that higher mortar volumes increase energy dissipation but reduce interfacial stiffness, offering insights for ...

Mezzo-scopic Analysis of Fracture Toughness in Steels
Materials Research, 2002 The cleavage fracture toughness of steels was mezzo-scopically analyzed on the basis of the statistical local fracture criterion approach. The statistical stress criterion at the crack tip region suggests that the cleavage fracture toughness in steels ...

On the influence of Al-concentration on the fracture toughness of NiAl: microcantilever fracture tests and atomistic simulations [PDF]
arXiv, 2019 The mechanical properties of the stoichiometric B2 $\beta$-phase of NiAl are well established, however the effect of off-stoichiometric composition on the fracture toughness has not yet been systematically studied over the entire composition range of 40-50% Al.

On the fracture toughness of snow [PDF]
Annals of Glaciology, 2004 AbstractThe release of a dry-snow slab avalanche involves brittle fracture. It is therefore essentially a non-linear fracture mechanics problem. Traditional snow-stability evaluation has mainly focused on snow strength measurements. Fracture toughness describes how well a material can withstand failure. The fracture toughness of snow is therefore a key
