Modeling three‐dimensional crack propagation—A comparison of crack path tracking strategies

International Journal for Numerical Methods in Engineering, 2008
AbstractThe development of a new finite element technique for the simulation of discontinuous failure phenomena in three dimensions is the key objective of this study. In contrast to the widely used extended finite element technique, we apply a purely deformation‐based strategy based on an independent interpolation of the deformation field on both ...

Fatigue crack propagation of planar three-dimensional cracks

International Journal of Fatigue, 2022
In this paper the Fourier series is used to evaluate mode I Stress Intensity Factors (SIF) in three-dimensional planar flaws based on a distortion transformation of a reference disc. Under the hypothesis of an isolated crack, the SIF at each point of the crack border is calculated to assess the crack shape after propagation according to the crack ...

Simulation of three-dimensional cracks

The Visual Computer, 2000
We describe a method for simulating the process of cracking based on a 3D physical model. Cracks appear when the stress caused by internal or external force exceeds the tolerable amount. We applied a spring network model to a simulation of cracks that appear on drying clay. Clay contracts, or shrinks, as it dries.

AN ANALYSIS FOR THREE DIMENSIONAL CRACKS

Fatigue & Fracture of Engineering Materials & Structures, 1994
Abstract— A new method of analysis is proposed for an infinite solid containing an embedded plane crack of arbitrary shape. The analysis is fundamentally based on the body force method, but proper expressions of the body force densities are introduced and the stress conditions of the crack surface are replaced by the resultant force conditions in order
