The Influence of Specimen Dimensions and Shape on the Results of Tensile Impact Tests

Abstract

The results of a study on the influence of specimen length, diameter, and cross-sectional shape on tensile impact tests are given. The effects of the ratio of length to diameter are discussed, as well as the effect of size in geometrically similar specimens, and the influence of cross-sectional shape. The results show that the effect of velocity on the tensile properties of metals is independent of bath the dimensions and the cross-sectional shape of the specimen. Furthermore, the critical velocity is not altered by these variables. For a given diameter and varying gage lengths, the stress-strain curves are nearly identical tip to the point where the tangent Is horizontal. Beyond this point, the shape of the curves is controlled by the necking.
