Two Circular-Hole Cracks of the Same Size in an Infinite Plate in Tension

This note is concerned with two circular-hole cracks of the same size in an infinite plate in tension by means of the generation of Bueckner's principle and the hybrid displacement discontinuity method. Many numerical results which can reveal the interactions of two circular-hole cracks are given.

Stress Concentration of Periodic Collinear Square Holes in an Infinite Plate in Tension

A numerical approach for the stress concentration of periodic collinear holes in an infinite plate in tension is presented. It involves the fictitious stress method and a generalization of Bueckner's principle. Numerical examples are concluded to show that the numerical approach is very efficient and accurate for analyzing the stress concentration of periodic collinear holes in an infinite plate in tension. The stress concentration of periodic collinear square holes in an infinite plate in tension is studied in detail by using the numerical approach. The calculated stress concentration factor is proven to be accurate.

A New Numerical Analysis for Inclined Crack in an Infinite Plate

This paper presents a numerical approach for modeling multiple crack fatigue growth in a plane elastic infinite plate. It involves a generation of Bueckner’s principle, In the numerical simulation, for each increment of crack extension, remeshing of existing boundaries is not necessary. Crack extension is modeled conveniently by adding new boundary elements on the incremental crack extension to the previous crack boundaries. At the same time, the element characters of some related elements are adjusted according to the manner in which the boundary element method is implemented. Fatigue growth of an inclined crack in a infinite plate under cyclic load is modeled to illustrate the effectiveness of the numerical approach.
