Two- and Three-Dimensional Numerical Investigation of the Influence of Holes on the Fatigue Crack Growth Path

Problems in fracture mechanics are difficult when the appropriate analysis is unspecified, which very common most real-life situations. Finite element modeling thus demonstrated to be an essential technique overcome these problems. There currently various software tools available for problems, but they usually use, and obtaining accurate results not obvious task. This paper illustrates some procedures two finite programs solve problems two- three-dimensional linear-elastic mechanics, educational proposal made use this a better understanding of mechanics. Crack was done variety ways depending on software. The first well-known ANSYS, utilized industry, second freely distributed code, called FRANC2D/L, from Cornell University. These applications were used predict fatigue crack growth path as well associated stress intensity factors. predicted demonstrate that turned towards hole. paths influenced by varying positions sizes single holes, while symmetrically holes have no effect direction. findings study agree with other experimental propagation studies presented literature reveal similar trajectory observations.
