INFLUENCE OF MATERIAL PARAMETER MISMATCH ON CRACK PROPAGATION IN COMPOSITE LAMINATES
Jixie qiangdu, 2022 The propagation path of cracks perpendicular to the interface of composite laminates usually takes many forms. By analyzing the stress field of crack tip during crack propagation, the driving force of crack tip is determined, in this way, the crack ...

On the Effects of Modeling As-Manufactured Geometry: Toward Digital Twin
International Journal of Aerospace Engineering, 2014 A simple, nonstandardized material test specimen, which fails along one of two different likely crack paths, is considered herein. The result of deviations in geometry on the order of tenths of a millimeter, this ambiguity in crack path motivates the ...

Crack-Path Analysis for Brittle and Non-Brittle Cracks: A Cell Method Approach
Computer Modeling in Engineering & Sciences, 2004 Defining the crack path in brittle and non-brittle crack is not easy, due to several unknowns. If the direction of crack propagation can be computed by means of one of the existing criteria, it is not known whether this direction will remain constant during crack propagation. A crack initiation leads to an enhanced stress field at crack tip.

Engineering Fracture Mechanics, 2010
The models of crack growth in mixed mode conditions are reviewed for the plane and three-dimensional (3D) states of stress. Both critical load value and crack path or surface growth are predicted by different criteria in terms of elastic singular stress states and T-stress component. Monotonic and cyclic loading induced crack growth is considered.

In responsible elements of the planes, bridges and other constructions from metal and composite materials the stress state in the tips of crack is mixed type. At that the conditions of rectilinear growth of a crack are violated as shown by numerous observations and experiments.

Abstract Crack paths are discussed from several different points of view. The remarkable reproducibility of crack paths, especially the frequent occurrence of straight cracks, is considered. The general dominance of mode I growth at mixed mode loading (via kinking or tilting of the crack edge) is examined, and it is shown that mode I growth can be ...
