An Analysis of Mode III Doubly Periodic Crack-Tip Field of Orthotropic Composite Materials

open access: yesJournal of Applied Mathematics, 2013
The mechanical behavior near the doubly periodic crack tips for orthotropic composite materials plate subjected to antiplane shear loading is studied. This is done by complex function theory and conformal mapping of the Jacobi elliptic function with the ...

Crack Spacing in Reinforced Concrete: Approximate Solution [PDF]

open access: yesJournal of Structural Engineering, 1983
In a companion paper by Bazant and Oh, a simplified theory for predicting the spacing of cracks in a parallel crack system in reinforced concrete was presented. In this paper a different approximate analysis yields about the same result. For this purpose, a solution based on the formulas for the stress caused by a concentrated force in a halfspace is ...

Modulating fracture toughness through processing-mediated mesostructure in additively manufactured Al-12Si alloy

open access: yesMaterials & Design, 2022
Al-12Si alloy processed through additive manufacturing exhibits a complex hierarchical structure. At the mesoscale, its melt pool boundaries constitute a network of weak interfaces that provides preferred pathways for crack kinking, leading to both ...

Crack analysis of concrete beams based on pseudo-discrete crack model [PDF]

open access: yes, 2015
Crack widths are important considerations in both serviceability and durability design of concrete structures and should be evaluated to ensure compliance with design limits.

Simple models of the hydrofracture process [PDF]

open access: yes, 2015
Hydrofracturing to recover natural gas and oil relies on the creation of a fracture network with pressurized water. We analyze the creation of the network in two ways.

Crack width and spacing measurement using deep learning and damage assessment for reinforced concrete non-structural wall

open access: yesCase Studies in Construction Materials
With technological advancements, the seismic resistance of reinforced concrete (RC) buildings has significantly increased. However, as the performance of structural members increases, damage to both structural and non-structural members becomes a severe ...

Annular cracks in thin films of nanoparticle suspensions drying on a fiber

open access: yes, 2013
We report an experimental study of the crack pattern formed during the drying of a colloidal suspension. A horizontal fiber, which provides a one dimensional, boundary-free substrate, is coated by a film of micronic thickness.
