Crack interaction with microstructure
Materials Today, 2007 Designing microstructure for damage tolerance requires a detailed understanding of how an advancing crack interacts with the microstructure (and sometimes modifies it locally) at multiple length scales. Advances in experimental techniques, such as the availability of well-controlled straining stages for optical and electron microscopes, the focused ion

Analysis on the fracture failure in crack interaction of mortar using the phase-field method [PDF]
工程科学学报, 2016 This article introduces a new mortar fracture analysis method based on the phase-field method,which is used to analyze the fracture failure in crack interaction of mortar.The non-conserved Allen-Cahn equation was adopted as the system governing equation ...

Journal of Materials Research and TechnologyFatigue crack propagation in polypropylene, despite its significance in a wide range of structural applications, has not been sufficiently researched because of the complex interaction between the crack tip and process zone ahead of the crack tip.

Atomistic Simulations of Dislocation - Crack Interaction
Journal of Solid Mechanics and Materials Engineering, 2007 The interaction of dislocations with a static mode I crack is studied by large scale molecular dynamics simulations. The model consists of a blunted [001](110) crack in nickel, to which after relaxation at K < K Ic the displacement field of a dislocation is added.

Crack interaction, coalescence and mixed mode fracture mechanics
, 1996 Multiple cracks are often observed in engineering structures; and their interaction and coalescence may significantly affect the lifetime of component or structure. In this paper, the general features associated with crack interaction and coalescence are

Metals, 2023 Weld defects such as porosity, inclusion, burn-through, and lack of penetration are difficult to detect and control effectively in an orthotropic steel deck (OSD), which will be a fatigue crack initiation site and lead to several fatigue cracking.

Crack Interaction Criteria in Pressure Vessels and Pipe
, 1995 An attempt was made to define a new crack interaction criterion for pressurized cylinders with two co-planar surface cracks. Elastic-plastic finite element method with line spring concept (line spring element method) was used to verify the validity of ...

Modeling of edge cracks interaction [PDF]
Fracture and Structural Integrity, 2016 From experimental and theoretical investigations it is known that cracks are sensitive to geometry, e.g., to the inclination angle to the load. A small deviation of a crack from the normal direction to a tensile load causes mixed mode conditions near the
