Stress analysis of an infinite rectangular plate perforated by two unequal circular holes under bi-axial uniform stresses

Yeong-Bin Yang and Jae-Hoon Kang

Abstract

Exact solutions for stresses for an infinite rectangular plate perforated by two circular holes of different radii subjected to uni-axial or bi-axial uniform loads are investigated using the Airy stress function. The hoop stresses occurring at the edge of the circular hole are computed and plotted. Comparisons are made for the stress concentration factors for several types of loading conditions.

Key Words

perforated plate; circular hole; multi-holes; biaxial tension; stress concentration factor; airy stress function; exact solution
