Cracking failure of curved hollow tree trunks [PDF]
Royal Society Open Science, 2020 Understanding the failure modes of curved hollow tree trunks is essential from both safety and conservation perspectives. Despite extensive research, the underlying mechanism that determines the cracking failure of curved hollow tree trunks remains unclear due to the lack of theoretical analysis that considers both the initial curvature ...

Considerations in selecting laboratory scale test specimens for evaluation of fracture toughness [PDF]
, 2013 The assessment of defects in large steel structures requires a trustworthy evaluation of the material’s toughness. This toughness is not only a material property but is also influenced by the loading conditions and geometry; the so-called constraint. The

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.

How Geometry Controls the Tearing of Adhesive Thin Films on Curved Surfaces [PDF]
, 2011 Flaps can be detached from a thin film glued on a solid substrate by tearing and peeling. For flat substrates, it has been shown that these flaps spontaneously narrow and collapse in pointy triangular shapes. Here we show that various shapes, triangular,

ANALYSIS OF APPROXIMATED CURVED CRACKS IN HOMOGENEOUS AND GRADED MATERIALS
Journal of Engineering, 2009 In this paper two stages of analysis are studied. In stage I, the influence of crack shape on the crack-tip stresses, critical loads and subsequent propagation direction is investigated via a simple analytical model for cracks in homogeneous materials ...

Curved Fatigue Cracks Under Complex Loading [PDF]
SAE Technical Paper Series, 2001 <div class="htmlview paragraph">A reliable and cost effective two-phase methodology is proposed to predict crack propagation life in generic two-dimensional structural components under complex fatigue loading. First, the usually curved fatigue crack path and its stress intensity factors are calculated at small crack increments in a specialized ...
