J. Pressure Vessel Technol 139(4), 044501 (Mar 10, 2017) (3 pages) Paper No: PVT-14-1193; doi: 10.1115/1.4035975 History: Received November 27, 2014; Revised January 19, 2017

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.
