Abstract
We suppose the disturbances for many circular holes-that are free boundary to an elastic medium (matrix) of infinite extent under in-plane problem. The matrix is subjected to arbitrary loading, for example, by uniform stresses. From past studies, we derive these general solutions for the theory of elasticity. We observe the stress around the holes from this solution and analysis of FEM (ANSYS). We focus on the disturbances of the stress due to the span between the circular holes, the circular holes size and arrangement pattern. In this paper, we analysis disturbances of stress by different arrangement pattern of the circular holes under the circular holes of same number. Several numerical examples are presented graphically. From the graphs, we consider validity of the theoretical solution of the theory of elasticity.
