CORRELATIONS BETWEEN TRANSVERSE AND TORSIONAL SHEAR CREEP DEFORMATIONS

摘要

The creep deformation of a rivet subjected to transverse shear depends, among other factors, upon the rivet diameter and rivet length. This influence of size means that each particular rivet configuration must be tested to obtain the transverse shear-creep deformation, A more basic approach would be to predict the transverse shear-creep of a rivet in terms of the more fundamental case of pure shear as represented by torsion. This report develops a theory for predicting the transverse shear-creep deformation of a rivet in terms of pure torsional shear-creep. The correlation of trans-verse shear and pure torsion shear is made based on both the torsion of a solid circular bar and the torsion of a thin-walled circular tube. From the theory developed, it is also possible to obtain the creep deflection of a rivet from the creep constants in pure shear or simple tension.
