The Poisson’s ratio effect on the stress distribution over the thickness of a V-notched plate

Abstract

The presence of a stress concentrator in the geometry of a body has the effect of increasing the intensity of the stress state leading to a decrease in the strength of the material. The evaluation of the normal stress and stress concentration factor over the thickness of a V-notch plate plays an important role in life prediction and structure design. The objectives of this study are to highlight and determine the distribution of normal stress and stress concentration factor over the thickness off late. The present work is based on a number of 25 simulations on rectangular V-notched plates subjected to tensile loading. The determination of the stress state and the stress concentration factor was carried out based on numerical methods with finite element method.
