Experimental and simulation study on Ⅰ-Ⅱ mixed-mode fatigue crack growth of TC4-DT welded joint
Journal of Aeronautical Materials, 2020 The crack growth in the structure shows the complex Ⅰ-Ⅱ mixed-mode under the combined tensile and shear fatigue loading. It is of great significance to understand its growth law for evaluating the fatigue life of structures accurately.

Crack paths in composite materials [PDF]
Engineering Fracture Mechanics, 2010 Composites are often exposed to harsh loading conditions. This may lead to crack formation and propagation. In this paper an algorithm is described to predict the path of pre-existing cracks in homogeneous materials, based on an incremental approach. The approach is shown to also deal with the highly heterogeneous behaviour of periodically distributed ...

Crack tip fields in elastic-plastic and mixed mode I+II+III conditions, finite elements simulations and modeling [PDF]
Fracture and Structural Integrity, 2015 This paper is devoted to the analysis of the load path effect on I+II+III mixed mode fatigue crack propagation in a 316L stainless steel. Experiments were conducted in mode I+II and in mode I+II+III.

Crack paths in soft thin sheets
Fracture and Structural Integrity, 2019 Highly deformable materials (elastomers, gels, biological tissues, etc.) are ubiquitous in nature as well as in technology. The understanding of their flaw sensitivity is crucial to ensure a desired safety level.

Crack Path Prediction in Anisotropic Brittle Materials [PDF]
Physical Review Letters, 2005 A force balance condition to predict quasistatic crack paths in anisotropic brittle materials is derived from an analysis of diffuse interface continuum models that describe both short-scale failure inside a microscopic process zone and macroscopic linear elasticity.

Some practical crack path examples [PDF]
Fracture and Structural Integrity, 2007 It is well known that many engineering structures and components, as well as consumer items, contain cracks or crack-like flaws. It is widely recognised that crack growth must be considered both in designand in the analysis of failures.

Investigation of crack paths in natural fibre-reinforced composites [PDF]
Fracture and Structural Integrity, 2015 Nowadays, fibre-reinforced composite materials are widely used in many fields, e.g. automotive and aerospace. Natural fibres such as flax and hemp provide good density specific mechanical properties.
