Unloading-Induced Crack Propagation of Two Collinear Unequal Length Flaws in Brittle Rocks
Geofluids, 2020 The propagation and coalescence of numerous discontinuous joints significantly contribute to landslide instability during excavation unloading. The tip expression of stress intensity factors of two collinear unequal length cracks in a typical rock mass ...

An adaptive space-time phase field formulation for dynamic fracture of brittle shells based on LR NURBS [PDF]
, 2020 We present an adaptive space-time phase field formulation for dynamic fracture of brittle shells. Their deformation is characterized by the Kirchhoff–Love thin shell theory using a curvilinear surface description.

Interaction of Multiple Cracks on Crack Propagation.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2000 There is interaction among multiple cracks which are initiated in a plane surface by fatigue or environmentally assisted cracking. And it is observed that these cracks may coalesce as they approach each other. In this study, the interaction of multiple cracks with different relative locations and lengths was evaluated using a finite element method ...

Interaction Analysis of Non-aligned Cracks Using Extended Finite Element Method
Latin American Journal of Solids and StructuresMultiple flaws are frequently occurred in actual components, such as pressure vessels and power plants. These flaws will in some circumstances lead to more severe effects than single flaw alone.

Crack Front Waves and the dynamics of a rapidly moving crack
, 2001 Crack front waves are localized waves that propagate along the leading edge of a crack. They are generated by the interaction of a crack with a localized material inhomogeneity.
