Stresses Around an Annular Inclusion in a Strip Under Tension

Abstract

A two-dimensional solution in series form is given for the stresses and displacements around an annular inclusion perfectly bonded to an infinite strip under tension. The known solutions for an infinite plate with a reinforced circular hole and a strip with a central hole are obtained as limiting cases. Numerical results are given for the variations of stresses for various values of parameters which define the geometry and the elastic properties of the strip and the inclusion. The effect of reinforcement with beads is also discussed.
