De-localizing brittle fracture [PDF]

open access: yesJournal of the Mechanics and Physics of Solids, 2021
Extreme localization of damage in conventional brittle materials is the source of a host of undesirable effects. We show how artificially engineered metamaterials with all brittle constituents can be designed to ensure that every breakable sub-element fails independently.

Effects of High Toughness and Welding Residual Stress for Unstable Fracture Prevention

open access: yesApplied Sciences, 2020
Unstable fractures generally occur in brittle materials under low-temperature service conditions. Toughness and welding residual stress are the main factors that should be evaluated when defining a brittle crack propagation path. In this study, a rainbow

Main controlling factors of natural fractures in tight reservoirs of the lucaogou formation in the jimsar sag, Xinjiang, China

open access: yesFrontiers in Earth Science, 2023
Natural fractures act as critical flow channels and reservoir space in the Lucaogou Formation tight reservoir of the Jimsar Sag. It is essential to identify the main controlling factors of natural fractures in order to achieve efficient development of ...

Investigation on the Applicability of Several Fracture Criteria to the Mixed Mode Brittle Fractures

open access: yesAdvances in Mechanical Engineering, 2013
Mixed mode brittle fractures are very common failure behavior for cracked brittle materials under loading, and therefore, the prediction of the mixed mode brittle fractures is significant.

Fracture mechanics of micro samples: Fundamental considerations

open access: yesMaterials & Design, 2018
In this review article we consider the crack growth resistance of micrometer and sub-micrometer sized samples from the fracture mechanics point of view. Standard fracture mechanics test procedures were developed for macro-scale samples, and reduction of ...

Experimental conditions affecting the measured fracture toughness at the microscale: Notch geometry and crack extension measurement

open access: yesMaterials & Design, 2020
Experimental fracture mechanics at the microscale became an indispensable tool for understanding and developing advanced material systems. In case of linear elastic fracture mechanics, stringent requirements are typically only warranted for very brittle ...

Setting of Natural Fracture Splitting Surface on Connecting Rod and Its Formation Mechanism

open access: yesMetals, 2020
To break through the limitation of fracture splitting process on material selection and solve problems during fracture splitting such as parts tearing, failing to split, dropping dregs, fracture surface deformation and so on, a new technique of setting ...

Brittle Crack Arrest Temperature Estimation Method Utilizing a Small-Scale Test with a Thick Steel Plate for Shipbuilding

open access: yesMetals, 2023
As the shipbuilding industry has emerged from an extended recession, orders for high-value-added ships, such as LNG and ultra-large container ships, are increasing. For ultra-large container ships, high-strength, thick materials are applied.
