Kinking of a Crack Out of an Interface [PDF]

open access: yesJournal of Applied Mechanics, 1989
Kinking of a plane strain crack out of the interface between two dissimilar isotropic elastic solids is analyzed. The focus is on the initiation of kinking and thus the segment of the crack leaving the interface is imagined to be short compared to the segment in the interface.

A Criterion for Crack Kinking Out of an Interface [PDF]

open access: yesKey Engineering Materials, 2008
Cotterell and Rice theory (1980) on the kinking of a crack submitted to a biaxial loading in a homogeneous material has been recently revisited (Leguillon and Murer 2008). The mixed criterion for fracture which involves both an energetic and a stress condition (Leguillon 2002) allows defining a positive threshold of the T-stress below which no ...

Application of Interfacial Propagation and Kinking Crack Concept to ECC/Concrete Overlay Repair System [PDF]

open access: yesAdvances in Materials Science and Engineering, 2014
Research on the application of ultraductile engineered cementitious composite (ECC) as overlay in the repair of deteriorated concrete structures is performed in this paper. Also, interfacial crack kinking and trapping mechanism experimentally observed in

Novel micro-scale specimens for mode-dependent fracture testing of brittle materials: A case study on GaAs single crystals

open access: yesMaterials & Design, 2020
To study microscale fracture behavior under mode II and mode III loading new sample geometries are proposed. Finite element simulations were carried out to determine the mode I, II and III stress intensity factor distributions over the sample width as ...

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 ...

In-situ investigate on the microstructure evolution, deformation and fracture mechanism of Mg-Gd-Zn-Mn alloy with varies of LPSO volume fraction

open access: yesJournal of Materials Research and Technology, 2023
The induction of long-period stacking ordered (LPSO) phase through heat treatment was an effective method to strengthen magnesium alloys. In this study, the volume fraction of lamellar LPSO in the Mg-4Gd-1Zn-0.5Mn alloy was controlled by optimizing the ...

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide-Angle X-Ray Scattering. [PDF]

open access: yesAdv Sci (Weinh)
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Kinking conditions for running cracks [PDF]

open access: yesLe Journal de Physique IV, 1994
The problem of the abrupt change of the direction of a crack, propagating with high velocity, is studied in the present work. The study is based on a unified approach of the directional instability phenomena, which accompany running cracks. According to this approach, the running tip is simulated by a prebranched configuration, consisted of two ...

Effect of temperature on crack kinking and jumping in a cross-ply laminated beam

open access: yesArchives of Mechanics, 2016
To understand the mechanisms of crack kinking and jumping that occur within the 90° layer of a cross-ply fiber reinforced plastic laminated plate, double cantilever beam tests were performed at several temperatures for laminated plates with two types of ...
