THE SIZE EFFECT ON THE CONCENTRATION OF STRESS AND STRAIN IN FINITE THICKNESS ELASTIC PLATE CONTAINING A CIRCULAR HOLE

摘要：

The elastic stress and strain fields of different size plate with a hole subjected to tension are investigated using 3D finite element method. It is found that the stress and strain concentration factor of the finite thickness plate are different even if the plate is in elasticity state. The maximum stress and strain concentration factors do not always occur on the mid plane of the plate. The maximum stress in a finite thickness plate is higher than the one in the plane stress or plane strain states. The differences between maximum and surface value of stress concentration factor increase with thickness and this difference of stress concentration factor is larger than the one of strain concentration factor in the same plate.
